+1. Edit your subversion config ~/.subversion/config and set the following in each section:
+
+[miscellany]
+enable-auto-props = yes
+
+[auto-props]
+*.bat = svn:keywords=Id Revision;svn:eol-style=LF
+*.java = svn:keywords=Id Revision;svn:eol-style=LF
+*.sh = svn:keywords=Id Revision;svn:eol-style=LF
+*.txt = svn:keywords=Id Revision;svn:eol-style=LF
+*.wsdl = svn:keywords=Id Revision;svn:eol-style=LF
+*.xml = svn:keywords=Id Revision;svn:eol-style=LF
+*.xsd = svn:keywords=Id Revision;svn:eol-style=LF
+
+2. If you are using an IDE, make sure that it refers to the same config. So, 
+for example, if you are using Eclipse with Subclipse on windows, you need to
+set Team->SVN->Configuration Location to:
+
+/home/<your user name>/.subversion
+
+3. If you are using Eclipse, set your code style to jbpm.code.templates.xml with 
+Window --> Preferences --> Java --> Code Style --> Formatter --> Import

+/**
+ * maintains contextual information for a thread in a set of
+ * {@link Context}s.
+ * 
+ * <h3>Introduction</h3>
+ * 
+ * <p>Objects have different lifecycles and different context's (aka scopes).  An 
+ * environment provides the structure to easily manage objects with different 
+ * contexts.
+ * </p>
+ * 
+ * <p>Examples of contexts are: 
+ * <ul>
+ *   <li><b>process-engine</b>: The process-engine context is used to store e.g. data sources,
+ *     session factories and other static resources needed by an application.
+ *     The process-engine context lives for the complete duration of the {@link EnvironmentFactory}.  
+ *     So if the {@link EnvironmentFactory} is maintained in a static member field, the 
+ *     process-engine context lives for the duration of the application.
+ *     The same process-engine context is shared for all the Environments produced by one 
+ *     EnvironmentFactory.</li>
+ *   <li><b>environment</b>: The environment context is used for e.g. a transaction 
+ *     and transactional resources, user authentication.  This results in an efficient and 
+ *     configurable use of transactional resources that need to be lazily initialized.</li>
+ *   <li>The environment can accomodate other contexts as well.  They can be added 
+ *     and removed dynamically.  Examples of other potential contexts are web-request, web-session, 
+ *     web-application, business processDefinition, jobImpl, ... </li>
+ * </ul>    
+ *      
+ * <center><img src="environment.gif"/></center>
+ * 
+ * <p>An environment is typically installed like this
+ * </p>
+ * 
+ * <b><pre>static EnvironmentFactory environmentFactory = new DefaultEnvironmentFactory();
+ * 
+ * ...
+ * 
+ * Environment environment = environmentFactory.openEnvironment();
+ * try {
+ * 
+ *   ... everything available in this block ... 
+ * 
+ * } finally {
+ *   environment.close();
+ * }
+ * </pre></b>
+ *
+ * <h3>Purpose</h3>
+ * 
+ * <p>The first purpose of the environment is to separate the application from the 
+ * environment.  Standard Java and Enterprise Java are quite different and an environment 
+ * abstraction like this allows for the development of applications that can run in 
+ * both Standard and Enterprise environments.  Also test environments are easier to 
+ * tweak this way. 
+ * </p>
+ * 
+ * <p>A second purpose of the environment is to enable specific to global searching 
+ * of resources.  E.g. you could search for an 'adminEmailAddress' in the contexts
+ * 'execution', 'transaction' and 'process-engine' in the given order.
+ * That way, a global adminEmailAddress can be specified in the process-engine context 
+ * and it can be refined in more specific contexts.
+ * </p>
+ * 
+ * <h3>Search order</h3>
+ * 
+ * <p>To find an object in the environment, a searchOrder can be specified.  A 
+ * search order is an sequence that specifies the order in which the contexts should
+ * be searched.
+ * </p>
+ * 
+ * <p>The default search order is the inverse sequence of how the contexts are 
+ * added to the environment.  This is because in general, we can assume that the 
+ * more recent a context was added, the more specific it is. 
+ * </p>
+ *
+ * <h3>Transaction, username and classloader</h3>
+ * 
+ * <p>Three objects are used so frequently in an environment that they get 
+ * special treatment:
+ * </p>
+ * 
+ * <ul>
+ *   <li><b>Transaction</b>: an abstraction for marking a transaction with 
+ *   setRollbackOnly.</li>
+ *   <li><b>Classloader</b>: the current class loader.</li>
+ *   <li><b>Username</b>: the name of the currently authenticated user.</li>
+ * </ul>
+ * 
+ * <p>For these special properties, setters are also available.  That is to support 
+ * programmatic injection into the environment.  Alternatively, they can be configured
+ * in one of the contexts. 
+ * </p>
+ * 
+ * 
+ * @see EnvironmentFactory

+    <p>There are three main ways to create an object: by constructor or by a factory 
+    object or a static factory method.</p>
+    <p><b>Using the constructor</b>: Then the <code>class</code> attribute must provide the 
+    fully qualified class name.  In case another constructor then the default is 
+    targetted, a <code>constructor</code> child element can be provided.
+    The <code>factory</code> attribute should not be provided for using a constructor. 
+    </p>
+    <p><b>Using a factory</b>: Then the <code>factory</code> attribute or one 
+    <code>factory</code> element must be provided along with the attribute 
+    <code>method</code>. 
+    </p>
+    <p><b>Using a static factory method</b>: Then the <code>class</code> and 
+    <code>method</code> attributes should be specified.  There should be no 
+    reference to a <code>factory</code> attribute of element. 
+    </p>
+    <p><b>Construction and initialization</b>: all objects (constructor and factory)
+    are build in two phases: construction and initialisation phase.  During construction
+    all is done until a pointer is obtained to the object.  In initialisation, operations 
+    are applied to the object until it is ready to be used.  The separation between 
+    construction and initialisation is made to allow for bidirectional references.  In 
+    that case, at least one of both ends can not be fully initialised before it is injected 
+    into the other end.
+    </p>
+    <p><b>Operations</b>: after construction, various operations can be applied to objects 
+    like e.g. direct field injection, injection through setters, method invocation, 
+    enlist with the standard transaction, subscribe the object as a listener to an observable  
+    </p>
+    <p><b>Arguments</b>: There are two different places for arguments.  The <code>arg</code> 
+    elements for the factory method invocation should be placed as child elements under the 
+    <code>object</code> element.  The <code>arg</code> elements for the constructor should be 
+    placed as child elements under the <code>constructor</code> element.

+---------
+Utitlity module to create/drop the jBPM4 database schema.
+
+Usage
+-----
+Database creation can be triggered through the maven command line
+usally as part of the test preparation:
+
+	mvn -P<drop|create>-tables -Ddatabase=<database> install
+
+Supported databases
+-------------------
+
+- hsqldb
+- mysql
+- postgresql
+- oracle
+- sybase
+
+
+FAQ
+---
+
+1.) How is the default hypersonic database created?
+
+The default hypersonic is created within the jpdl module, as part of the jpdl test execution.
+See the connetion URL 'jdbc:hsqldb:file:@project.build.directory@/hypersonic/jbpm4DB' whereas
+'project.build.directory' in that case is 'modules/jpdl/target'

+    <title>What is it</title>
+    <para>In essence, the Process Virtual Machine is a framework specifying executable 
+    graphs.  A process definition represents an execution flow and has a structure that 
+    be represented graphically as a diagram.    
+    </para>  
+    <figure id="example.process.graph">
+      <title>Example process definition</title>
+      <mediaobject><imageobject><imagedata align="center" fileref="images/process.loan.png"/></imageobject></mediaobject>
+    </figure>
+    <para>Typically, process definitions are static.  A process definition is composed of 
+    activities and transitions.  The runtime behaviour of a activity is encapsulated in a so called 
+    Activity and it's decoupled from the process graph structure.  
+    </para>
+    <figure id="class.diagram.process.definition">
+      <title>Process structure class diagram</title>
+      <mediaobject><imageobject><imagedata align="center" fileref="images/class.diagram.process.definition.png"/></imageobject></mediaobject>
+    </figure>
+    <para>The Process Virtual 
+    Machine doesn't contain any such activity implementations.  It only provides the 
+    execution environment and an activity API to write <literal>Activity</literal> 
+    implementations as Java components.  Activities can also be wait states.  This means 
+    that the activity control flow goes outside the process system. For example a human task 
+    or invoking an service asynchronously.
+    </para>
+    <para>Many executions can be started for one process definition. An execution is a pointer 
+    that keeps track of the current activity.

+    </figure>
+    <para>To represent concurrent paths of execution, there is 
+    a hierarchical parent-child relation between so that one process instance can cope with concurrent 
+    paths of execution.

+    <title>Purpose</title>
+    <para>The Process Virtual Machine is designed in such a way that it's easy to build 
+    workflow, BPM, orchestration and other graph based execution langauges on top 
+    of it.  Examples of languages that have been built on top of this library:
+    </para>
+    <itemizedlist>
+      <listitem>jPDL: Workflow language that combines powerful human task capabilities with easy binding to Java.</listitem>
+      <listitem>BPEL: Web-Service orchestration (to be exact for the purists: BPEL is a WSDL service orchestration language)</listitem>
+      <listitem>Pageflow: To describe navigation handling in a web application, pages can be seen as activities and the nagivation between the pages as transitions.</listitem>
+      <listitem>XPDL: A graph based process language standardized by the Workflow Management Coalition (WfMC)</listitem>
+    </itemizedlist>
+    <para>Even while the nature of these languages is already very diverse, these are 
+    all examples of general purpose workflow languages.  The real power of the 
+    Process Virtual Machine is that it's very easy to build Domain Specific Languages (DSL)
+    with it.  For instance, it's very easy to build a very simple (and dedicated) workflow 
+    language to specify approvals related to documents in a document management system.
+    </para>
+    <para>BPM as a discipline refers to the management level effort to optimise efficiency
+    of an organisation by analysing and optimising the procedures of how people and systems 
+    work together. In designing the Process Virtual Machine and the jPDL language 
+    in particular, we have spend great care on facilitating the link between BPM analysis 
+    notations and executable process languages.  Here are the most known modeling notations: 
+    </para>
+    <itemizedlist>
+      <listitem>BPMN: OMG latest notation for modeling business processes.  
+      This is a modeling notation that is targetted explicitely to be bound 
+      to executable processes.
+      </listitem>
+      <listitem>UML activity diagrams: OMG notation for modeling business 
+      processes.  Mostly used in business context.</listitem>
+      <listitem>UML state diagrams: OMG modeling notation for defining technical 
+      state machines.  More used in a technical context.</listitem>
+      <listitem>EPC: Event driven process chains.  Rich notation for modeling 
+      business processes driven by SAP and IDS Scheer.</listitem>

+  <title>Execution modes</title>

+  <para>There are basically three process execution modes: object, persistent 
+  and embedded.  For the persistent and embedded execution modes, the process 
+  execution has to participate in a transaction.  In that case, the process 
+  execution has to take place inside of an Environment.  The environment will be 
+  used to bind process execution updates to a transaction in the application

+      for building an object graph that represents a process definition.

+      activity implementations will be covered in more depth later.
+      </para>
+      <para>The <literal>processDefinition</literal> object serves as a factory for process 
+      instance objects.  A process instance represents one execution of the process definition.
+      More precise, the process instance is the main path of execution.  
+      </para>

+      </para>  
+      <para>The <literal>execution</literal> can be seen as a state machine that operates as 
+      described in the process definition.  Starting a process 
+      instance means that the initial activity of the process definition is executed.
+      Since this is an automatic activity, the execution will proceed to the 
+      <literal>evaluate</literal> activity.  The <literal>evaluate</literal> activity is a wait state.
+      When the execution arrived at the evaluate activity, the method <literal>startProcessInstance</literal>
+      will return and waits until an external signal is provided with the <literal>signal</literal>
+      method.  So after the <literal>startProcessInstance</literal> we can verify if the 
+      execution is positioned in the evaluate activity.

+      <para>To make the process execute further, we provide an external trigger with the

+      </para>
+      <programlisting>execution.signal("approve");</programlisting>
+      <para>The <literal>WaitState</literal> activity implementation will take the transition 
+      that corresponds to the given signalName.  So the execution will first execute 
+      the automatic activity <literal>wire money</literal> and then return after entering 
+      the next wait state <literal>archive</literal>.
+      </para>
+      <programlisting>assertEquals("archive", execution.getActivityName());</programlisting>
+      <para>When the execution is waiting in the archive activity, the default signal will

+      <programlisting>execution.signal();

+      <para>The process has executed in the thread of the client.  The 
+      <literal>startProcessInstance</literal> method only returned when the <literal>evaluate</literal> 
+      activity was reached.  In other words, the <literal>ClientProcessDefinition.startProcessInstance</literal>

+    <para>The activity API is used to implement the runtime behaviour of activities.  So a activity

+    interface.  Activity implementations can control the flow of execution.
+    </para>  
+    <para>The event listener API serves to write pieces of Java code that should be executed upon

+    a activity.  It is very similar to the activity API, but the difference is  
+    that the propagation of the execution flow cannot be controlled.  E.g. when an execution 
+    is taking a transition, a listener to that event can be notified, but since the

+    standard Java, enterprise Java, SEAM and Spring.
+    </para>
+    <para>The PVM code itself will only use transactional resources through self-defined 
+    interfaces.  For example, the PVM itself has interfaces for some methods on the hibernate 
+    session, a async messaging session and a timer session.
+    </para>
+    <para>The environment allows to configure the actual implementations, lazy 
+    initialization of the services on a request-basis and caching the service 
+    objects for the duration of the transaction.

+    <para>We'll start with a very original hello world example.  A Display 
+    activity will print a message to the console:
+    </para>
+    <programlisting>public <emphasis role="bold">class Display</emphasis> implements <emphasis role="bold">Activity</emphasis> {
+
+  String message;
+
+  public Display(String message) {
+    this.message = message;
+  }
+
+  public void execute(ActivityExecution execution) {
+    <emphasis role="bold">System.out.println(message);</emphasis>
+  }
+}</programlisting>
+    <para>Let' build our first process definition with this activity:</para>
+    <figure id="activity.example">
+      <title>Display example process</title>
+      <mediaobject><imageobject><imagedata align="center" fileref="images/process.ab.png"/></imageobject></mediaobject>

+    <programlisting>ClientProcessDefinition processDefinition = ProcessFactory.build()

+      .transition().to("b")
+    .<emphasis role="bold">activity("b")</emphasis>.behaviour(<emphasis role="bold">new Display("world")</emphasis>)
+.done();</programlisting>
+    <para>Now we can execute this process as follows:</para>
+    <programlisting>Execution execution = processDefinition.startExecution();</programlisting>
+    <para>The invocation of <literal>startExecution</literal> will print hello world to the console:</para>
+    <programlisting>hello
+world</programlisting>
+    <para>One thing already worth noticing is that activities can be configured 
+    with properties.  In the Display example, you can see that the message property 
+    is configured differently in the two usages.  With configuration properties 
+    it becomes possible to write reusable activities. They can then be configured 
+    differently each time they are used in a process.  That is an essential part of 
+    how process languages can be build on top of the Process Virtual Machine.
+    </para>
+    <para>The other part that needs explanation is that this activity 
+    implementation does not contain any instructions for the propagation of the
+    execution.  When a new process instance is started, the execution is positioned
+    in the initial activity and that activity is executed.  The method 
+    <literal>Display.execute</literal> makes use of what is called implicit propagation 
+    of execution.  Concretely this means that the activity itself does not 
+    invoke any of the methods on the execution to propagate it.  In that case 
+    implicit propagation kicks in.  Implicit propagation will take the first 
+    transition if there is one.  If not, it will end the execution.  This explains 
+    why both activities <literal>a</literal> and <literal>b</literal> are executed and that 
+    the execution stops after activity <literal>b</literal> is executed.

+  <!-- ### ExternalActivity ############################################### -->
+  <section id="externalactivity">
+    <title>ExternalActivity</title>
+    <para>External activities are activities for which the responsibility for proceeding 
+    the execution is transferred externally, meaning outside the process system. This 
+    means that for the system that is executing the process, it's a wait state.  The 
+    execution will wait until an external trigger is given.  
+    </para>
+    <para>For dealing with external triggers, <literal>ExternalActivity</literal> 
+    adds two methods to the <literal>Activity</literal>:</para>
+    <programlisting>public <emphasis role="bold">interface ExternalActivity</emphasis> extends <emphasis role="bold">Activity</emphasis> {
+
+  void <emphasis role="bold">signal</emphasis>(Execution execution,
+              String signal, 
+              Map&lt;String, Object&gt; parameters) throws Exception;
+              
+}</programlisting>
+    <para>Just like with plain activities, when an execution arrives in a activity, the 
+    <literal>execute</literal>-method of the activity behaviour is invoked.
+    In external activities, the execute method typically does something to 
+    transfer the responsibility to another system and then enters a wait 
+    state by invoking <literal>execution.waitForSignal()</literal>.  For 
+    example in the execute method, responsibility could be transferred to a 
+    person by creating a task entry in a task management system and then
+    wait until the person completes the task.
+    </para>
+    <para>In case a activity behaves as a wait state, then the execution will 
+    wait in that activity until the execution's <literal>signal</literal> method 
+    is invoked.  The execution will delegate that signal to the behaviour Activity 
+    of the current activity.
+    </para>
+    <para>So the Activity's <literal>signal</literal>-method is invoked 
+    when the execution receives an external trigger during the wait state.  With the 
+    signal method, responsibility is transferred back to the process execution. For 
+    example, when a person completes a task, the task management system calls the 
+    signal method on the execution.
+    </para>  
+    <para>A signal can optionally have a signal name and a map of parameters.  Most 
+    common way on how activity behaviours interprete the signal and parameters is that 
+    the signal relates to the outgoing transition that needs to be taken and that the 
+    parameters are set as variables on the execution. But those are just examples, it 
+    is up to the activity to use the signal and the parameters as it pleases.

+    <para>Here's the same simple process that has a transition from a to b.  This

+    will invoke the <literal>ActivityExecution.take(String transitionName)</literal>.

+    <para>Building process graphs in Java code can be tedious because you have to keep track of all the

+    <para>For more details about the ProcessFactory, see <ulink url="../../api/org/jbpm/pvm/package-summary.html">the

+    <para>The initial activity <literal>submit loan request</literal> and the activity

+    message to the console.  But the witty reader can imagine an alternative 
+    <literal>Activity</literal> implementation that uses the Java API of a payment 
+    processing library to make a real automatic payment.  
+    </para>
+    <para>A new execution for the process above can be started like this

+    </figure>
+    <para>Now, the execution is at an interesting point.  There are two transitions out of 
+    the state <literal>evaluate</literal>.  One transition is called <literal>approve</literal> 
+    and one transition is called <literal>reject</literal>.  As we explained above, the WaitState
+    implementation will take the transition that corresponds to the signal that is given.  
+    Let's feed in the 'approve' signal like this:
+    </para>
+    <programlisting>execution.signal("approve");</programlisting>
+    <para>The <literal>approve</literal> signal will cause the execution to take the <literal>approve</literal>
+    transition and it will arrive in the activity <literal>wire money</literal>.
+    </para>
+    <para>In activity <literal>wire money</literal>, the message will be printed to the console.
+    Since, the <literal>Display</literal> activity didn't invoke the

+  <!-- ### EVENT PROPAGATION ############################################## -->
+  <section>
+    <title>Event propagation</title>
+    <para>Events are by default propagated to enclosing process elements.  The motivation 
+    is to allow for listeners on process definitions or composite activities that get executed
+    for all events that occur within that process element.  For example this feature 
+    allows to register an event listener on a process definition or a composite activity on 
+    <literal>end</literal> events.  Such action will be executed if that activity is 
+    left.  And if that event listener is registered on a composite activity, it will also be executed 
+    for all activities that are left within that composite activity. 
+    </para>
+    <para>To show this clearly, we'll create a <literal>DisplaySource</literal> event listener
+    that will print the message <literal>leaving</literal> and the source of the event
+    to the console.
+    </para>

+}</programlisting>
+    <para>Note that the purpose of event listeners is not to be visible, that's why the event listener 
+    itself should not be displayed in the diagram. A <literal>DisplaySource</literal> event listener
+    will be added as a listener to the event <literal>end</literal> on the composite activity.  
+    </para>
+    <para>The next process shows how the <literal>DisplaySource</literal> event listener is registered 
+    as a listener to to the 'end' event on the <literal>composite</literal> activity:</para>

+    </figure>
+    <programlisting>TODO update code snippet</programlisting>
+    <para>Next we'll start an execution.</para>
+    <programlisting>ClientExecution execution = processDefinition.startProcessInstance();</programlisting>
+    <para>After starting a new execution, the execution will be in activity <literal>a</literal> as 
+    that is the initial activity.  No activities have been left so no message is logged.  Next a signal 
+    will be given to the execution, causing it to take the transition from <literal>a</literal>
+    to <literal>b</literal>.
+    </para>
+    <programlisting>execution.signal();</programlisting>  
+    <para>When the signal method returns, the execution will have taken the transition and 
+    the <literal>end</literal> event will be fired on activity <literal>a</literal>.  That 
+    event will be propagated to the 
+    composite activity and to the process definition.  Since our <literal>DisplaySource</literal> 
+    event listener is placed 
+    on the <literal>composite</literal> activity, it will receive the event and print the following 
+    message on the console:
+    </para>
+    <programlisting>leaving activity(a)</programlisting>
+    <para>Another</para>
+    <programlisting>execution.signal();</programlisting>
+    <para>will take the transition from b to c.  That will fire two activity-leave events.  One on  
+    activity b and one on activity composite.  So the following lines will be appended to the console 
+    output:</para>  
+    <programlisting>leaving activity(b)
+leaving activity(composite)</programlisting>
+    <para>Event propagation is build on the hierarchical composition structure of the process 
+    definition.  The top level element is always the process definition.  The process 
+    definition contains a list of activities.  Each activity can be a leaf activity or it can be a 
+    composite activity, which means that it contains a list of nested activities.  Nested activities 
+    can be used for e.g. super states or composite activities in nested process languages like BPEL.    
+    </para>
+    <para>So the even model also works similarly for composite activities as it did for the process 
+    definition above.  Suppose that 'Phase one' models 
+    a super state as in state machines.  Then event propagation allows to subscribe to all events 
+    within that super state.  The idea is that the hierarchical composition corresponds to 
+    diagram representation. If an element 'e' is drawn inside another element 'p', then p 
+    is the parent of e. A process definition has a set of top level activities.  Every activity can have 
+    a set of nested activities.  The parent of a transition is considered as the first common 
+    parent for it's source and destination.  
+    </para>
+    <para>If an event listener is not interested in propagated events, propagation can be disabled 
+    with <literal>propagationDisabled()</literal> while building the process with the 
+    <literal>ProcessFactory</literal>.  The next process is the same process 
+    as above except that propagated events will be disabled on the event listener.  The graph diagram

+    <para>This section explains how the Process Virtual Machine boroughs the thread

+    <para>When a client invokes a method (like e.g. the signal method) on an execution, 
+    by default, the Process Virtual Machine will use that thread to progress the execution
+    until it reached a wait state.  Once the next wait state has been reached, the 
+    method returns and the client gets the thread back.  This is the default way 
+    for the Process Virtual Machine to operate.  Two more levels of asynchonous 
+    execution complement this default behaviour:

+    <para>Starting a new execution means that the initial activity is executed.  So if an automatic

+    is taken.  This happens all inside of the invocation of <literal>startProcessInstance</literal>.
+    </para>
+    <para>In this case however, the initial activity is a wait state.  So 
+    the method <literal>startProcessInstance</literal> returns immediately and the execution will be 
+    positioned in the initial activity 'wait 1'.
+    </para>

+      <mediaobject><imageobject><imagedata align="center" fileref="images/execution.automatic.wait1.png"/></imageobject></mediaobject>
+    </figure>
+    <para>Then an external trigger is given with the signal method.</para>
+    <programlisting>execution.signal();</programlisting>
+    <para>As explained above when <link linkend="externalactivityexample">introducing the WaitState</link>, 
+    that signal will cause the default transition to be taken.  The 
+    transition will move the execution to activity <literal>automatic 1</literal> and execute it.  
+    The execute method of the <literal>Display</literal> activity in <literal>automatic 1</literal> 
+    print a line to the console and it will <emphasis role="bold">not</emphasis> call 
+    <literal>execution.waitForSignal()</literal>.  Therefore, the execution will proceed by 
+    taking the default transition out of <literal>automatic 1</literal>.  At this stage, the 
+    signal method is still blocking.  Another way to think about it is that the execution 
+    methods like <literal>signal</literal> will use the thread of the client to interpret 
+    the process definition until a wait state is reached.   
+    </para>
+    <para>Then the execution arrives in <literal>wait 2</literal> and executes 
+    the <literal>WaitState</literal> activity.  That method will invoke 
+    the <literal>execution.waitForSignal()</literal>, which will cause the signal method 
+    to return.  That is when the thread is given back to the client that invoked the 
+    <literal>signal</literal> method.
+    </para>
+    <para>So when the signal method returns, the execution is positioned in <literal>wait 2</literal>.</para>

+      <mediaobject><imageobject><imagedata align="center" fileref="images/execution.automatic.wait2.png"/></imageobject></mediaobject>
+    </figure>
+    <para>Then the execution is now waiting for an external trigger just as an object 
+    (more precisely an object graph) in memory until the next external trigger is given 
+    with the signal method.
+    </para>
+    <programlisting>execution.signal();</programlisting>
+    <para>This second invocation of signal will take the execution similarly all the

+    <para>The benefits of using this paradigm is that the same process definition 
+    can be executed in <link linkend="clientexecutionmode">client execution mode</link> 
+    (in-memory without persistence) as well as in <link linkend="persistentexecutionmode">
+    persistent execution mode</link>, depending on the application and on the environment.
+    </para>
+    <para>When executing a process in persistent mode, this is how you typically want 
+    to bind that process execution to transactions of the database:
+    </para>
+    <figure id="transactions.png">

+      <mediaobject><imageobject><imagedata align="center" fileref="images/transactions.png"/></imageobject></mediaobject>
+    </figure>
+    <para>In most situations, the computational work that needs to be done as part of 
+    the process after an external trigger (the red pieces) is pretty minimal.  Typically 
+    transactions combining the process execution and processing the request from the 
+    UI takes typically less then a second.  Whereas the wait state in business processes 
+    typically can span for hours, days or even years.  The clue is to clearly distinct 
+    when a wait state starts so that only the computational work done before the start 
+    of that wait state should be included in the transaction.  
+    </para>
+    <para>Think of 
+    it this way: &quot;When an approval arrives, what are all the automated processing that 
+    needs to be done before the process system needs to wait for another external 
+    trigger?&quot;  Unless pdf's need to be generated or mass emails need to be send,
+    the amount of time that this takes is usually neglectable.  That is why in the 
+    default persistent execution mode, the process work is executed in the thread 
+    of the client.
+    </para>
+    <para>This reasoning even holds in case of concurrent paths of execution.  
+    When a single path of execution splits into concurrent paths of execution,
+    the process overhead of calculating that is neglectable.  So that is why it 
+    makes sense for a fork or split activity implementation that targets persistent 
+    execution mode to spawn the concurrent paths sequentially in the same thread.
+    Basically it's all just computational work as part of the same transaction.
+    This can only be done because the fork/split knows that each concurrent path 
+    of execution will return whenever a wait state is encountered. 
+    </para>
+    <para>Since this is a difficult concept to grasp, I'll explain it again with other 
+    words.  Look at it from the overhead that is produced by the process execution 
+    itself in persistent execution mode.  If in a transaction, an execution is given 
+    an external trigger and that causes the execution to split into multiple concurrent 
+    paths of execution.  Then the process overhead of calculating this is neglectable. 
+    Also the overhead of the generated SQL is neglectable.  And since all the work done 
+    in the concurrent branches must be done inside that single transaction, there is 
+    typically no point in having fork/split implementations spawn the concurrent 
+    paths of execution in multiple threads. 
+    </para>
+    <para>To make executable processes, developers need to know exactly what the automatic activities
+    are, what the wait states are and which threads will be allocated to the process execution.  
+    For business analysts that draw the analysis process, things are a bit simpler.   For the  
+    activities they draw, they usually know whether it's a human or a system that is responsible.
+    But they typically don't not how this translates to threads and transactions.
+    </para>
+    <para>So for the developer, the first job is to analyse what needs to be executed 
+    within the thread of control of the process and what is outside.  Looking for the external 
+    triggers can be a good start to find the wait states in a process, just like verbs and nouns 
+    can be the rule of thumb in building UML class diagrams. 
+    </para>

+  
+  <!-- ### PROCESS CONCURRENCY ############################################ -->
+  <section>
+    <title>Process concurrency</title>
+    <para>To model process concurrency, there is a parent-child tree structure on the 
+    execution. The idea is that the main path of execution is the root of that tree.
+    The main path of execution is also called the process instance.  It is the execution 
+    that is created when starting or creating a new process instance for a given  
+    process definition. 
+    </para>
+    <para>Now, because the main path of execution is the same object as the 
+    process instance, this keeps the usage simple in case of simple processes 
+    without concurrency. 
+    </para>
+    <figure id="execution.structure">
+      <title>UML class diagram of the basic execution structure</title>
+      <mediaobject><imageobject><imagedata align="center" fileref="images/class.diagram.process.execution.png"/></imageobject></mediaobject>
+    </figure>
+    <para>To establish multiple concurrent paths of execution, activity implementations 
+    like a fork or split can create child executions with method 
+    <literal>ActivityExecution.createExecution</literal>.  Activity implementations 
+    like join or merge can stop these concurrent paths of execution by calling 
+    method <literal>stop</literal> on the concurrent execution.  
+    </para>
+    <para>Only leaf executions can be active.  Non-leave executions should be 
+    inactive.  This tree structure of executions doesn't enforce a particular type of 
+    concurrency or join behaviour.  It's up to the forks or and-splits and to the joins 
+    or and-merges to use the execution tree structure in any way they want to define 
+    the wanted concurrency behaviour.  Here you see an example 
+    of concurrent executions. 
+    </para>
+    <figure id="concurrency">
+      <title>Concurrent paths of execution</title>
+      <mediaobject><imageobject><imagedata align="center" fileref="images/execution.concurrency.png"/></imageobject></mediaobject>
+    </figure>
+    <para>There is a billing and a shipping path of execution.  In this case, the 
+    flat bar activities represent activities that fork and join.  The execution shows a three 
+    executions.  The main path of execution is inactive (represented as gray) and the 
+    billing and shipping paths of execution are active and point to the activity 
+    <literal>bill</literal> and <literal>ship</literal> respectively.
+    </para>
+    <para>It's up to the activity behaviour implementations how they want to use this 
+    execution structure.  Suppose that multiple tasks have to be completed before the 
+    execution is to proceed.  The activity behaviour can spawn a series of child executions 
+    for this.  Or alternatively, the task component could support task groups that 
+    are associated to one single execution.  In that case, the task component becomes
+    responsible for synchronizing the tasks, thereby moving this responsibility 
+    outside the scope of the execution tree structure.
+    </para>
+  </section>
+
+  <!-- ### EXCEPTION HANDLERS ############################################# -->
+  <section>
+    <title>Exception handlers</title>
+    <para>In all the code that is associated to a process
+    like <literal>Activity</literal>s, <literal>EventListeners</literal> and 
+    <literal>Condition</literal>s, it's possible to associate exception handlers.  This 
+    can be thought of as including try-catch blocks in 
+    the method implementations of those implementations.  But in order to build more reusable building 
+    blocks for both the delegation classes and the exception handling logic, exception handlers are 
+    added to the core process model. 
+    </para>
+    <para>An exception handler can be associated to any process element.  When an exception 
+    occurs in a delegation class, a matching exception handler will be searched for.  If 
+    such an exception handler is found, it will get a chance to handle the exception.
+    </para>
+    <para>If an exception handler completes without problems, then the exception is considered 
+    handled and the execution resumes right after the delegation code that was called.  For example,
+    a transition has three actions and the second action throws an exception that is handled 
+    by an exception handler, then   
+    </para>
+    <para>Writing automatic activities that are exception handler aware is easy.  The 
+    default is to proceed anyway.  No method needs to be called on the execution.  So 
+    if an automatic activity throws an exception that is handled by an exception handler,
+    the execution will just proceed after that activity.  It becomes a big more difficult 
+    for control flow activities.  They might have to include try-finally blocks to 
+    invoke the proper methods on the execution before an exception handler gets a 
+    chance to handle the exception.  For example, if an activity is a wait state and 
+    an exception occurs, then there is a risk that the thread jumps over the 
+    invocation of <literal>execution.waitForSignal()</literal>, causing the execution 
+    to proceed after the activity.

+    </para> 
+    <para>When a new execution is created, it is in STATE_ACTIVE. To change 
+    the state to a locked state, use lock(String). Some STATE_* constants 
+    are provided that represent the most commonly used locked states. But

+    <para>If an execution is locked, methods that change the execution will 
+    throw a PvmException and the message will reference the actual locking state. 
+    Firing events, updating variables, updating priority and adding comments 
+    are not considered to change an execution. Also creation and removal of child 
+    executions are unchecked, which means that those methods can be invoked by 
+    external API clients and activity behaviour methods, even while the execution 
+    is in a locked state.
+    </para> 
+    <para>Make sure that comparisons between getState() and the STATE_* constants 
+    are done with .equals and not with '==' because if executions are loaded 
+    from persistent storage, a new string is created instead of the constants.
+    </para>

+    <itemizedlist>
+      <listitem>When it is ended</listitem>
+      <listitem>When it is suspended</listitem>
+      <listitem>During asynchronous continuations</listitem>
+    </itemizedlist>
+    <para>Furthermore, locking can be used by Activity implementations to make 
+    executions read only during wait states hen responsibility for the execution is 
+    transferred to an external entity such as:
+    </para>
+    <itemizedlist>
+      <listitem>A human task</listitem>
+      <listitem>A service invocation</listitem>
+      <listitem>A wait state that ends when a scanner detects that a file appears</listitem>
+    </itemizedlist>
+    <para>In these situations the strategy is that the external entity should get 
+    full control over the execution because it wants to control what is allowed 
+    and what not.  To get that control, they lock the execution so that all interactions 
+    have to go through the external entity. 
+    </para>
+    <para>One of the main reasons to create external entities is that they can live
+    on after the execution has already proceeded.  For example, in case 
+    of a service invocation, a timer could cause the execution to take the timeout transition.
+    When the response arrives after the timeout, the service invocation entity should 
+    make sure it doesn't signal the execution.  So the service invocation can be 
+    seen as a activity instance (aka activity instance) and is unique for every execution 
+    of the activity.
+    </para>
+    <para>External entities themselves are responsible for managing the execution 
+    lock.  If the timers and client applications are consequent in addressing the 
+    external entities instead of the execution directly, then locking is in theory 
+    unnecessary.  It's up to the activity behaviour implementations whether they want 
+    to take the overhead of locking and unlocking.

+    <para>The environment is partitioned into a set of contexts.  Each context

+    strech over the full lifetime of the application.  The block context only

+    <para>An <literal>EnvironmentFactory</literal> is typically obtained by

+    <programlisting>public class <emphasis role="bold">Book</emphasis> {
+  ...
+  public Book() {}
+  ...
+}</programlisting>
+    <para>Then let's create an environment factory that knows how to create book</para>
+    <programlisting>static EnvironmentFactory environmentFactory = EnvironmentFactory.parseXmlString(

+    "&lt;/jbpm-configuration&gt;"
+));</programlisting>
+    <para>Now we'll create an environment block with this environment factory and 
+    we'll look up the book in the environment.  First the lookup is done by 
+    type and secondly by name.
+    </para>
+    <programlisting>Environment environment = environmentFactory.openEnvironment();

+  
+  assertSame(book, <emphasis role="bold">environment.get("book")</emphasis>);
+  
+} finally {
+  environment.close();
+}</programlisting>
+    <para>To prevent that you have to pass the environment as a parameter in 
+    all methods, the current environment is maintained in a threadlocal stack:
+    </para>
+    <programlisting>Environment environment = Environment.getCurrent();</programlisting>
+  </section>
+  
+  <section id="context">
+    <title>Context</title>
+    <para>Contexts can be added and removed dynamically.  Anything can be exposed

+    <programlisting>public interface <emphasis role="bold">Context</emphasis> {

+    <para>When doing a lookup on the environment, there is a default search order 
+    in which the contexts will be scanned for the requested object.  The default

+    if an object is defined in both the process-engine context and in the block context,
+    the block context is considered more applicable and that will be scanned first.

+    </figure>
+    <para>The activities in the three activities will be wait states just like 
+    in <xref linkend="externalactivityexample" /> 
+    </para>
+    <para>To make sure we can persist this class, we create the hibernate mapping for 
+    it and add it to the configuration like this:
+    </para>
+    <programlisting>&lt;hibernate-configuration&gt;
+  &lt;properties resource=&quot;hibernate.properties&quot; /&gt;
+  &lt;mapping resource=&quot;jbpm.pvm.typedefs.hbm.xml&quot; /&gt;

+&lt;/hibernate-configuration&gt;</programlisting>
+    <para>The next code pieces show the contents of one unit test method.  The method 
+    will first create the environment factory. Then, in a first transaction, a process 
+    definition will be created and saved into the database.  Then the next transaction will 
+    create a new execution of that process.  And the following two transactions will 
+    provide external triggers to the execution.
+    </para>
+    <programlisting>EnvironmentFactory environmentFactory = EnvironmentFactory.parse(new ResourceStreamSource(
+    "org/jbpm/examples/ch09/environment.cfg.xml"
+));</programlisting>
+    <para>Then in a first transaction, a process is created and saved in the database.
+    This is typically referred to as deploying a process and it only needs to be done 
+    once.
+    </para>
+    <programlisting>Environment environment = environmentFactory.openEnvironment();

+}</programlisting>
+    <para>In the previous transaction, the process definition, the activities and transitions 
+    will be inserted into the database tables.
+    </para>
+    <para>Next we'll show how a new process execution can be started for this 
+    process definition.  Note that in this case, we provide <link linkend="businesskey">a 
+    business key</link> called 'first'.  This will make it easy for us to retrieve 
+    the same execution from the database in subsequent transactions.  After starting 
+    the new process execution, it will wait in activity 'one' cause the behaviour is a 
+    wait state.
+    </para>

+  pvmDbSession.save(execution);
+
+} finally {
+  environment.close();
+}</programlisting>
+    <para>In the previous transaction, a new execution record will be inserted into 
+    the database.
+    </para>
+    <para>Next we feed in an external trigger into this existing process execution.
+    We load the execution, provide a signal and just save it back into the database.
+    </para>
+    <programlisting>environment = environmentFactory.openEnvironment();
+try {
+  PvmDbSession pvmDbSession = environment.get(PvmDbSession.class);

+  assertNotNull(execution);
+  assertEquals("one", execution.getActivity().getName());
+

+  // it reaches the next wait state
+  execution.signal();
+
+  assertEquals("two", execution.getActivity().getName());
+
+  pvmDbSession.save(execution);
+
+} finally {
+  environment.close();
+}</programlisting>
+    <para>The previous transaction will result in an update of the existing

+    the activity table.

+    <programlisting>UPDATE JBPM_EXECUTION 
+SET
+  NODE_=?,
+  DBVERSION_=?,
+  ...
+WHERE DBID_=? 
+  AND DBVERSION_=?</programlisting>
+    <para>The version in this SQL shows the automatic optimistic locking that 
+    is baked into the PVM persistence so that process persistence can easily 
+    scale to multiple JVM's or multiple machines.
+    </para>
+    <para>In the example code, there is one more transaction that is 
+    completely similar to the previous which takes the execution from 
+    activity 'two' to activity 'three'. 
+    </para>
+    <para>All of this shows that the PVM can move from one wait state to 
+    another wait state transactionally.  Each transaction correcponds to 
+    a state transition.
+    </para>
+    <para>Note that in case of automatic activities, multiple activities 
+    will be executed before the execution reaches a wait state.  Typically 
+    that is desired behaviour.  In case the automatic activities take too 
+    long or you don't want to block the original transaction to wait for 
+    the completion of those automatic activities, check out <xref linkend="asynchronouscontinuations"/>
+    to learn about how it's possible to demarcate transactions in the process 
+    definition, which can also be seen as safe-points during process execution.

+LICENSE AGREEMENT
+JBOSS(r)
+
+This License Agreement governs the use of the Software Packages and any updates to the Software 
+Packages, regardless of the delivery mechanism.  Each Software Package is a collective work 
+under U.S. Copyright Law.  Subject to the following terms, Red Hat, Inc. ("Red Hat") grants to 
+the user ("Client") a license to the applicable collective work(s) pursuant to the 
+GNU Lesser General Public License v. 2.1 except for the following Software Packages: 
+(a) JBoss Portal Forums and JBoss Transactions JTS, each of which is licensed pursuant to the 
+GNU General Public License v.2; 
+
+(b) JBoss Rules, which is licensed pursuant to the Apache  License v.2.0;
+
+(c) an optional download for JBoss Cache for the Berkeley DB for Java database, which is licensed under the 
+(open source) Sleepycat License (if Client does not wish to use the open source version of this database, 
+it may purchase a license from Sleepycat Software); 
+
+and (d) the BPEL extension for JBoss jBPM, which is licensed under the Common Public License v.1, 
+and, pursuant to the OASIS BPEL4WS standard, requires parties wishing to redistribute to enter various 
+royalty-free patent licenses.  
+
+Each of the foregoing licenses is available at http://www.opensource.org/licenses/index.php.
+
+1.  The Software.  "Software Packages" refer to the various software modules that are created and made available 
+for distribution by the JBoss.org open source community at http://www.jboss.org.   Each of the Software Packages 
+may be comprised of hundreds of software components.  The end user license agreement for each component is located in 
+the component's source code.  With the exception of certain image files identified in Section 2 below, 
+the license terms for the components permit Client to copy, modify, and redistribute the component, 
+in both source code and binary code forms.  This agreement does not limit Client's rights under, 
+or grant Client rights that supersede, the license terms of any particular component.
+
+2.  Intellectual Property Rights.  The Software Packages are owned by Red Hat and others and are protected under copyright 
+and other laws.  Title to the Software Packages and any component, or to any copy, modification, or merged portion shall 
+remain with the aforementioned, subject to the applicable license.  The "JBoss" trademark, "Red Hat" trademark, the 
+individual Software Package trademarks, and the "Shadowman" logo are registered trademarks of Red Hat and its affiliates 
+in the U.S. and other countries.  This agreement permits Client to distribute unmodified copies of the Software Packages 
+using the Red Hat trademarks that Red Hat has inserted in the Software Packages on the condition that Client follows Red Hat's 
+trademark guidelines for those trademarks located at http://www.redhat.com/about/corporate/trademark/.  Client must abide by 
+these trademark guidelines when distributing the Software Packages, regardless of whether the Software Packages have been modified. 
+If Client modifies the Software Packages, then Client must replace all Red Hat trademarks and logos identified at 
+http://www.jboss.com/company/logos, unless a separate agreement with Red Hat is executed or other permission granted.  
+Merely deleting the files containing the Red Hat trademarks may corrupt the Software Packages.  
+
+3.  Limited Warranty.  Except as specifically stated in this Paragraph 3 or a license for a particular 
+component, to the maximum extent permitted under applicable law, the Software Packages and the 
+components are provided and licensed "as is" without warranty of any kind, expressed or implied, 
+including the implied warranties of merchantability, non-infringement or fitness for a particular purpose.  
+Red Hat warrants that the media on which Software Packages may be furnished will be free from defects in 
+materials and manufacture under normal use for a period of 30 days from the date of delivery to Client.  
+Red Hat does not warrant that the functions contained in the Software Packages will meet Client's requirements 
+or that the operation of the Software Packages will be entirely error free or appear precisely as described 
+in the accompanying documentation. This warranty extends only to the party that purchases the Services 
+pertaining to the Software Packages from Red Hat or a Red Hat authorized distributor. 
+
+4.  Limitation of Remedies and Liability. To the maximum extent permitted by applicable law, the remedies 
+described below are accepted by Client as its only remedies.  Red Hat's entire liability, and Client's 
+exclusive remedies, shall be: If the Software media is defective, Client may return it within 30 days of 
+delivery along with a copy of Client's payment receipt and Red Hat, at its option, will replace it or 
+refund the money paid by Client for the Software.  To the maximum extent permitted by applicable law, 
+Red Hat or any Red Hat authorized dealer will not be liable to Client for any incidental or consequential 
+damages, including lost profits or lost savings arising out of the use or inability to use the Software, 
+even if Red Hat or such dealer has been advised of the possibility of such damages.  In no event shall 
+Red Hat's liability under this agreement exceed the amount that Client paid to Red Hat under this 
+Agreement during the twelve months preceding the action.
+
+5.  Export Control.  As required by U.S. law, Client represents and warrants that it: 
+(a) understands that the Software Packages are subject to export controls under the 
+U.S. Commerce Department's Export Administration Regulations ("EAR"); 
+
+(b) is not located in a prohibited destination country under the EAR or U.S. sanctions regulations 
+(currently Cuba, Iran, Iraq, Libya, North Korea, Sudan and Syria); 
+
+(c) will not export, re-export, or transfer the Software Packages to any prohibited destination, entity, 
+or individual without the necessary export license(s) or authorizations(s) from the U.S. Government; 
+
+(d) will not use or transfer the Software Packages for use in any sensitive nuclear, chemical or 
+biological weapons, or missile technology end-uses unless authorized by the U.S. Government by 
+regulation or specific license; 
+
+(e) understands and agrees that if it is in the United States and exports or transfers the Software 
+Packages to eligible end users, it will, as required by EAR Section 740.17(e), submit semi-annual 
+reports to the Commerce Department's Bureau of Industry & Security (BIS), which include the name and 
+address (including country) of each transferee; 
+
+and (f) understands that countries other than the United States may restrict the import, use, or 
+export of encryption products and that it shall be solely responsible for compliance with any such 
+import, use, or export restrictions.
+
+6.  Third Party Programs. Red Hat may distribute third party software programs with the Software Packages 
+that are not part of the Software Packages and which Client must install separately.  These third party 
+programs are subject to their own license terms.  The license terms either accompany the programs or 
+can be viewed at http://www.redhat.com/licenses/.  If Client does not agree to abide by the applicable 
+license terms for such programs, then Client may not install them.  If Client wishes to install the programs 
+on more than one system or transfer the programs to another party, then Client must contact the licensor 
+of the programs.
+
+7.  General.  If any provision of this agreement is held to be unenforceable, that shall not affect the 
+enforceability of the remaining provisions.  This License Agreement shall be governed by the laws of the 
+State of North Carolina and of the United States, without regard to any conflict of laws provisions, 
+except that the United Nations Convention on the International Sale of Goods shall not apply.

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990
+  Ty Coon, President of Vice
+
+That's all there is to it!

+Tests in the enterprise module are integration tests. The maven surefire plugin
+runs tests during the 'test' phase by default. This module is configured to
+skip test execution during the 'test' phase, allowing the build to reach the
+'package' phase and assemble the ejb jar.
+
+Enterprise tests are associated to the 'integration-test' phase that occurs
+after 'package' but before 'install'. In order to run properly, enterprise
+tests require a running JBoss application server. The address to which the
+server is bound must be specified in the Maven property 'jboss.bind.address',
+otherwise the tests will be skipped.
+
+mvn -Djboss.bind.address=127.0.0.1 test
+
+Because several databases do not allow DDL in JTA transactions, the database
+schema has to be created prior to executing the tests for the first time,
+unless you've chosen Hsql as the target database when running the installer.

+default implementation of process execution in {@link org.jbpm.pvm.internal.model.ExecutionImpl} 
+based on {@link org.jbpm.pvm.internal.model.AtomicOperation}s
+
+<h3>Bidirectional relations</h3>
+<p>In this process model thoughout the pvm codebase, there are several bidirectional 
+relations.  By convention, the bidirectional relations are maintained on the many side.
+This means that when you call for example {@link org.jbpm.pvm.internal.model.ProcessDefinitionImpl#addActivity(org.jbpm.pvm.internal.model.ActivityImpl)}, that 
+method will also update the inverse pointer by invoking the 
+{@link org.jbpm.pvm.internal.model.ActivityImpl#setProcessDefinition(org.jbpm.pvm.internal.model.ProcessDefinitionImpl)} setter.  Setter methods will be plain setter 
+methods and they will NOT update the inverse reference.  (that would cause 
+an infinite loop).
+</p>
+
+<p>In the same spirit, there is the convention that the many side of bidirection 
+relations provide factory methods for the related objects.  Those factory methods 
+will also establish the bidirectional relation.  E.g. {@link org.jbpm.pvm.internal.model.ProcessDefinitionImpl#createActivity(String)}.

+/**
+ * object factory that creates, initializes, wires and caches objects
+ * based on {@link Descriptor descriptors} (aka IoC container).
+ *
+ * <h3>General principle</h3>
+ *
+ * <p>As input, a WireContext takes a {@link WireDefinition}.  The WireDefinition contains
+ * named {@link Descriptor}s that know how to create objects and wire them together.
+ * Each object has a name.  The WireContext will maintain a cache (map) of the created
+ * objects.  So that upon subsequent requests, the same object can be given from the cache.
+ * </p>
+ *
+ * <center><img src="wirescope.gif"/></center>
+ *
+ * <h3>Purpose</h3>
+ * 
+ * <p>A WireContext is used often in combination with {@link Environment} to 
+ * decouple the processDefinition virtual machine from its environment.  In the 
+ * {@link JbpmConfiguration}, both the process-engine context and 
+ * the environment contexts are WireContexts.  The PVM will use the persistence service, 
+ * asynchronous message service, timer service and other services through specified 
+ * abstractions in the environment.
+ * </p>
+ * 
+ * <p>Another usage of the WireContext is construction and configuration of user 
+ * code objects in a persistable way.  {@link ActivityBehaviour}s and {@link org.jbpm.activity.ExternalActivityBehaviour}
+ * and other user code can be instantiated with a WireContext.  That way, they can 
+ * be persisted in a fixed schema.    
+ * </p>
+ * 
+ * <p>Each {@link ProcessElementImpl} has configuration properties.
+ * Consider this extra metadata that can be associated to elements in a processDefinition definition.
+ * In that respect, it's somewhat similar to what annotations are in Java.  Because of the wire 
+ * persistence, all these configuration properties fit into the same process model and in its 
+ * database schema.  
+ * </p>
+ *
+ * <h3>Xml</h3>
+ * <p>Mostly often, {@link Descriptor}s and WireContext's are not used
+ * directly.  Instead, the wire XML is used in a configuration file.
+ * The {@link WireParser wire XML parser} contains the documentation on
+ * the XML grammer.  The {@link WireParser} will produce a {@link WireDefinition}
+ * with a bunch of {@link Descriptor}s in it.
+ *
+ * <h3 id="lifecycle">Object lifecycle</h3>
+ *
+ * <p>Objects are build in 2 phases: construction and initialization.
+ * The motivation for splitting these phases is to resolve many of the
+ * circular dependencies.  Imagine 2 objects that have a bidirectional
+ * reference.  By splitting the construction from the initialization
+ * phase, the objects can both be constructed first, and then during
+ * initialization, they will be injected into each other.
+ * </p>
+ *
+ * <h3>Construction</h3>
+ * <p>Construction of the object is all that needs to be done until a
+ * reference to the object is available.
+ * </p>
+ *
+ * <p>In the case of dynamically created
+ * objects ({@link ObjectDescriptor}), the simplest case this is
+ * accomplished with a constructor.  But also static or non-static factory
+ * methods can be used to obtain a reference to an object.
+ * </p>
+ *
+ * <p>In case of immutable objects, the descriptor can just provide a reference
+ * to a singleton object.
+ * </p>
+ *
+ * <h3>Initialization</h3>
+ * <p>Initialization is optional and it is comprised of everything that needs
+ * to be done with an object after a reference to the object is available.
+ * {@link AbstractDescriptor} contains an empty default initialization method.
+ * </p>
+ *
+ * <p>For objects {@link ObjectDescriptor}s, this means that a a
+ * sequence of {@link Operation}s can be applied to the object.  Following
+ * operations implementations are already available and can be applied to
+ * an object during initialization:
+ * </p>
+ *
+ * <ul>
+ *   <li><b>{@link FieldOperation}</b>: injects another object into a field</li>
+ *   <li><b>{@link PropertyOperation}</b>: injects another object with a setter method.</li>
+ *   <li><b>{@link InvokeOperation}</b>: invokes a method.</li>
+ *   <li><b>{@link SubscribeOperation}</b>: subscribes to an {@link Observable observable}.</li>
+ * </ul>
+ *
+ * <h3>Environment</h3>
+ *
+ * <p>When an environment is injected into a WireContext, lookup of all
+ * referenced object names will be done first in this WireContext, but
+ * if the object name is not defined there, the environment will be
+ * searched in the environment's default search order.
+ * </p>
+ *
+ * <h3>Events</h3>
+ * <p>Several objects will fire events to which can be subscribed:
+ * </p>
+ *
+ * <p>The WireContext itself fires the {@link #EVENT_OPEN} and {@link #EVENT_OPEN}
+ * events.
+ * </p>
+ *
+ * <p>The {@link Descriptor}s will fire the events {@link Descriptor#EVENT_CONSTRUCTING},
+ * {@link Descriptor#EVENT_INITIALIZING}, {@link Descriptor#EVENT_CONSTRUCTED},
+ * {@link Descriptor#EVENT_SET} and {@link Descriptor#EVENT_REMOVE}.
+ * </p>
+ *
+ * <p>And last but not least, the objects created by the WireContext can be
+ * {@link Observable} themselves.
+ * </p>
+ *
+ * <h3>Eager initialization</h3>
+ * 
+ * <p>By default, all objects in a WireContext are lazily constructued and initialized.
+ * Eager initialization is specified on a named object and it means that the 
+ * object is constructed and initialized during construction of the WireContext.
+ * You an only specify eager initialization when the object has a name.
+ * </p>
+ * 
+ * <h3>Specifying how an object should be initialized.</h3>
+ *
+ * <p>The initialization can be specified with the {@link AbstractDescriptor#setInit(char)} method.</p>
+ * The possible value for <code>init</code> parameter is one of :
+ * <ul>
+ *   <li>{@link AbstractDescriptor#INIT_LAZY}: for lazy creation and delayed initialization</li>
+ *   <li>{@link AbstractDescriptor#INIT_REQUIRED}: for lazy creation and immediate initialization</li>
+ *   <li>{@link AbstractDescriptor#INIT_EAGER}: for eager creation and delayed initialization</li>
+ *   <li>{@link AbstractDescriptor#INIT_IMMEDIATE}: for eager creation and immediate initialization</li>
+ * </ul>

+ * <p>This {@link Binding} specifies {@link PropertyOperation} (for property injection).</p>
+ *
+ * <p>A property injection is defined by a <b><code>{@literal <property>}</code></b> xml element.</p>
+ *
+ * <p>This element must have a attribute "name" or a attribute "setter".
+ * <ul>
+ * <li>the "name" attribute specifies the name of the property to inject. For a property <code>foo</code>, a setter method named <code>setFoo</code> should exist.</li>
+ * <li>the "setter" attribute specifies the name of the setter method to use to inject the property.</li>
+ * </ul>
+ * If both attributes are present, the setter method is used.
+ * </p>
+ *
+ * <p>This element should contain a child element that defines a {@link Descriptor}.
+ * This descriptor will be used to create the object that will be assigned to the field</p>
+ *
+ * <h3>Example</h3>
+ *
+ * Consider the following class:
+ * <pre> public class Foo {
+ *   String bar;
+ *   public void setBar(String bar) {
+ *     this.bar = bar;
+ *   }
+ * }</pre>
+ *
+ * The following Xml declaration will create an object 'o' of class 'Foo' (see {@link org.jbpm.pvm.internal.wire.descriptor.ObjectDescriptor}), and
+ * the value <code>hello</code> will be assigned to <code>o.bar</code> by calling the <code>setBar</code> method.
+ *
+ * <pre> &lt;objects&gt;
+ *   &lt;object name='o' class='Foo'&gt;
+ *     &lt;property name='bar'&gt;
+ *       &lt;string value='hello' /&gt;
+ *     &lt;/property&gt;
+ *   &lt;/object&gt;

+ * <li>className ({@link #setClassName(String)})</li>
+ * <li>factoryObjectName ({@link #setFactoryObjectName(String)})</li>
+ * <li>factoryDescriptor ({@link #setFactoryDescriptor(Descriptor)})</li>
+ * </ul>
+ * Only one of these methods can be used.
+ * </p>
+ *
+ * <h3 id='create'>Creating objects</h3>
+ * <h4>Creating object from a constructor</h4>
+ *
+ * <p>This method is used when <code>{@link #getClassName()}!=null && {@link #getMethodName()}==null</code>.</p>
+ *
+ * <p>The {@link #construct(WireContext)} method creates a new object
+ * from a constructor matching the given arguments
+ * (specified with {@link #setArgDescriptors(List)}).</p>
+ *
+ *
+ * <h4>Creating an object from a method invocation</h4>
+ *
+ * <p>The name of the method to call is specified by the method attribute.</p>
+ * <ul>
+ * <li>If the method is <i>static</i>, the related class is {@link #getClassName()}.</li>
+ * <li>If the method is an object method, the object to which the method will be applied is defined by:
+ *  <ul>
+ *    <li>If <code>{@link #getFactoryObjectName()}!=null</code>: the object with the name factoryObjectName will be fetched from the context.</li>
+ *    <li>if <code>{@link #getFactoryDescriptor()}!=null</code>: the object will be created from the factory descriptor.</li>
+ *  </ul>
+ * </li>
+ * </ul>
+ * <p>The object returned by {@link #construct(WireContext)} is the object returned by the method invocation.</p>
+ *
+ *
+ * <h3>Initializing Objects</h3>
+ * <h4>Auto Wiring</h4>
+ * <p>If the auto wiring is enabled for the object (<code>{@link #isAutoWireEnabled()}==true</code>),
+ * the WireContext will try to look for objects with the same name as the fields in the class.
+ * If it finds an object with that name, and if it is assignable to the field's type, it is automatically injected,
+ * without the need for explicit {@link FieldOperation} that specifies the injection in the wiring xml.</p>
+ * <p>If the auto wiring is enabled and the WireContext finds an object with the name of a field, but not assignable to this field,
+ * a warning message is generated.</p>
+ *
+ * <p>Auto-wiring is disabled by default.</p>
+ *
+ * <h4>Operations</h4>
+ * <p>Field injection or property injection are done after the auto-wiring. For more information, see {@link Operation}.</p>
+ *
+ * <p>If a field was injected by auto-wiring, its value can be overridden by specifying
+ *  a {@link FieldOperation} or {@link PropertyOperation} operation.</p>

+ * <h3>Bindings</h3>
+ *
+ * <p>The defaults bindings for the Wiring XML are divided in two categories:
+ * </p>
+ *
+ * <ul>
+ * 	<li>Descriptors, registered with the {@link #CATEGORY_DESCRIPTOR} category</li>
+ * 	<li>Operations, registered with the {@link #CATEGORY_OPERATION} category</li>
+ * </ul>
+ *
+ * <p>Once a parser is created, bindings can be added, overwritten and removed
+ * to customize that parser instance.
+ * </p>
+ *
+ * <h3 id='args'>Describing arguments</h3>
+ *
+ * <p>An ArgDescriptor is defined by a <b><code>&lt;arg&gt;</code></b> xml element.</p>
+ *
+ * <p>This element can have an attribute "type", which specifies name of the argument's type.</p>
+ * <p>This element contains <b>one</b> child element that defines a {@link Descriptor}. This descriptor specifies the value to give to the argument.</p>
+ *
+ * <h4>Example</h4>
+ *
+ * Consider the following class:
+ * <pre> public class Hello {
+ *   public static String sayHello(String name) {
+ *     return "Hello " + name + " !";
+ *   }
+ * }</pre>
+ *
+ * The following Xml declaration will create an object 's' of class 'String' (see {@link ObjectDescriptor}).
+ * This object is created by invoking <code>Hello.sayHello</code> with the value <code>world</code> as a parameter.
+ *
+ * <pre> &lt;objects&gt;
+ *   &lt;object name="s" class='Hello' method='sayHello'&gt;
+ *     &lt;arg&gt;
+ *      &lt;string value='world' /&gt;
+ *     &lt;/arg&gt;
+ *   &lt;/object&gt;
+ * &lt;/objects&gt;</pre>
+ *
+ * The created object 's' will be a String, containing "Hello world !".
+ * 
+ * <h3 id='init'>Initialization</h3>
+ * 
+ * <p>The initialization method can be defined with the <code>init</code> attribute. 
+ * For more details on how initialization works, see section 'Initialization' of {@link WireContext}.</p>
+ * 
+ * The <code>init</code> attribute can have these values:
+ * <ul>
+ *   <li><code>lazy</code>: for lazy creation and delayed initialization</li>
+ *   <li><code>required</code>: for lazy creation and immediate initialization</li>
+ *   <li><code>eager</code>: for eager creation and delayed initialization</li>

+/** makes typical usage of JAXP more convenient, adds a binding framework, 
+ * entity resolution and error handling.
+ * 
+ * <h2>Purpose</h2>
+ * <p>This is a base parser for the common pattern where first JAXP is used
+ * to parse xml into a Document Object Model (DOM), and then, this DOM is
+ * examined to build a domain model object. The main purpose of this parser 
+ * is to serve as a base class for implementing such parsers and to provide 
+ * a more convenient API for working with JAXP.
+ * </p>
+ * 
+ * <p>A {@link Parser} is a thread safe object.  For each parse operation, a 
+ * new {@link Parse} object is created with method {@link #createParse()}.  
+ * Then the parse object is used to specify the input source, execute the 
+ * parse operation and extract the results. 
+ * </p>
+ * 
+ * <p>{@link Binding}s capture parsing of a certain element type. This way,
+ * the parser becomes more modular and customizable.
+ * </p>
+ * 
+ * <p>{@link Entity Entities} are schema's that specify the grammar of the 
+ * XML files that are parsed by the parser. 
+ * </p>
+ * 
+ * <h2>API Usage</h2>
+ * <p>Parsers can be customized by inheritance (that will be covered below), 
+ * but a parser can also be used as is:
+ * </p>
+ *
+ * <pre><i> 1 </i>|   static Parser parser = new Parser();
+ *<i> 2 </i>| 
+ *<i> 3 </i>|   void someMethod() {
+ *<i> 4 </i>|     MyDomainObject mdo = (MyDomainObject) parser
+ *<i> 5 </i>|             .createParse()
+ *<i> 6 </i>|             .setString(myXmlString)
+ *<i> 7 </i>|             .execute()
+ *<i> 8 </i>|             .checkProblems()
+ *<i> 9 </i>|             .getDocumentObject();
+ *<i>10 </i>|   }
+ * </pre>
+ * 
+ * <p><b>line 1</b> shows that a single parser can be used for all threads as 
+ * the parser is maintained in a static member field.
+ * </p>
+ *
+ * <p><b>line 5</b> shows that a new parse operation is always started with 
+ * the {@link #createParse()} operation.  The {@link Parse} object that is 
+ * returned will maintain all data that is related to that single parse 
+ * operation. 
+ * </p>
+ *
+ * <p><b>line 6</b> shows how a simple XML string can be provided as the input 
+ * source for the parse operation.  Alternative methods to specify the input 
+ * source are {@link Parse#setFile(java.io.File)}, 
+ * {@link Parse#setInputStream(java.io.InputStream)}, 
+ * {@link Parse#setInputSource(InputSource)},
+ * {@link Parse#setUrl(java.net.URL)} and
+ * {@link Parse#setStreamSource(StreamInput)}. 
+ * </p>
+ *
+ * <p><b>line 7</b> shows how the execution of the parse is performed.  The 
+ * input source will be read, the resulting Document Object Model (DOM) will 
+ * be walked and potentially problems are produced in the parse.
+ * </p>
+ *
+ * <p><b>line 8</b> shows how an exception can be thrown in case of an error.
+ * The parse execution itself tries to keep parsing as much as possible to 
+ * provide the developer with as much feedback as possible in one parse cycle.
+ * The {@link Parse#getProblems() problems} are silently captured in the parse
+ * object.  If an exception is thrown by 
+ * {@link #Parse#checkProblems(String, Parse)}, it will contain a report of 
+ * all the parsing problems.  Alternatively, the {@link Parse#hasProblems() problems
+ * in the parse object} could be examined directly without the need for an exception. 
+ * </p>
+ *
+ * <p><b>line 9</b> shows how the result of the parse operation is extracted 
+ * from the parse object.  
+ * </p>
+ * 
+ * <h2 id="binding">Binding</h2>
+ * <p>Bindings are the link between a certain type of element in your XML document
+ * and the corresponding java object in your domain model.</p>
+ *
+ * <p>A parser can be configured with a set of {@link Binding}s.  Each {@link Binding}
+ * knows how to transform a dom element of a given tagName to the corresponding Java
+ * object.  {@link Bindings} has a notion of binding categories.  For example, activities
+ * and actions can be seen as different categories in jPDL.
+ * </p>
+ *
+ * <p>The purpose of bindings is to make certain elements in the parsing configurable.
+ * E.g. in jPDL, the main structure of the document is fixed.  But activity types can be
+ * added dynamically.
+ * </p>
+ *
+ * <p>The current {@link Bindings} implementation only supports matching of an
+ * element with a {@link Binding} based on tagName.  If you want to take other things
+ * into account (e.g. when you want to differentiate between elements of the same
+ * tagName with a different attribute value), you can create a specialized
+ * {@link Bindings} class.</p>
+ *
+ * <p>Bindings are added by tagName, but they have to be looked up by element.  That is
+ * to support more specialized bindings implementations that match an element with a
+ * binding on more information then just the tagName.  In that case, a specialized subclass of
+ * {@link Binding} should be created and the method {@link #getBinding(Element, String)} and
+ * constructor {@link Bindings#Bindings(Bindings)} should be provided
+ * with the more specialized matching behaviour.
+ * </p>
+ *
+ * <h2 id="objectstack">Object stack</h2>
+ * <p>When implementing {@link Binding}s, you might want to make use of the
+ * contextual object stack that is provided on the {@link Parse}.  The
+ * {@link Binding} implementations can maintain Java objects on that stack
+ * that are being created.
+ * </p>
+ *
+ * <p>E.g. you could push the ProcessDefinition element onto the object stack while it
+ * is being parsed like this:
+ * </p>
+ *
+ * <pre>public class MyProcessBinding implements Binding {
+ *
+ *   public Object parse(Element element, Parse parse, Parser parser) {
+ *     <i>// instantiate the object for this binding</i>
+ *     MyProcess myProcess = new MyProcess();
+ *
+ *     <i>// collect all the child elements of element</i>
+ *     List<Element> elements = XmlUtil.elements(element);
+ *
+ *     <i>// push my processDefinition onto the object stack</i>
+ *     parse.pushObject(myProcess);
+ *     try {
+ *
+ *       for (Element activityElement: elements) {
+ *         // parse the child elements with the bindings in category "activity"
+ *         parseElement(activityElement, parse, "activity");
+ *       }
+ *     } finally {
+ *       // make sure my processDefinition is popped.
+ *       parse.popObject();
+ *     }
+ *     return myProcess;
+ *   }
+ * }
+ * </pre>
+ *
+ * <p>Then, activity bindings might access the processDefinition like this:
+ * </p>
+ *
+ * <pre>public class MyNodeBinding implements Binding {
+ *
+ *   public Object parse(Element element, Parse parse, Parser parser) {
+ *     <i>// instantiate the object for this binding</i>
+ *     MyNode myNode = new MyNode();
+ *
+ *     <i>// add the activity to the processDefinition</i>
+ *     MyProcess myProcess = parse.findObject(MyProcess.class);
+ *     myProcess.addNode(myNode);
+ *     myNode.setMyProcess(myProcess);
+ *
+ *     return myNode;
+ *   }
+ * }
+ * </pre>
+ *
+ * <p>A parser implementation will typically have a static Bindings object that
+ * is leveraged in all parser objects.   To customize bindings for a such a parser
+ * be sure to make a deep copy with {@link Bindings#Bindings(Bindings)} before
+ * you start adding more bindings to the specialized parser.  Otherwise the
+ * base parser's bindings will be updated as well.
+ * </p>
+ * 
+ * <h2 id="buildingcustomparsers">Building custom parsers</h2>
+ * 
+ * <p>This parser is build for inheritance.   
+ * Overriding method {@link #parseDocumentElement(Element, Parse)} can be an easy 
+ * way to start writing your own logic on walking the Document Object Model (DOM).
+ * Such customizations can still be combined with the usage of 
+ * <a href="#binding">bindings</a>.
+ * </p>
+ * 
+ * <h2 id="entityresolving">Entity resolving</h2>
+ * <p>A parser can be configured with a set of entities with the
+ * {@link #addEntity(String, Entity)} method.  The {@link UrlEntity} has
+ * a convenience method to build entities from resources
+ * {@link UrlEntity#UrlEntity(String, ClassLoader)}.
+ * </p>
+ *
+ * <p>When a document builder is created, the default implementation of the
+ * {@link #setEntityResolver(DocumentBuilder)} will set this parser as the entity resolver.
+ * The implementation method of {@link EntityResolver} ({@link #resolveEntity(String, String)}
+ * will use the added {@link Entity}s to try and find a match based on the
+ * publicId.  If one is found, the {@link Entity} inputSource is returned, otherwise
+ * the systemId is used.
+ * </p>
+ *
+ * <p>This class is intended to be used with aggregation as well as inheritence.

+/**
+ * Provides a parser and evaluator for unix-like cron expressions. Cron 
+ * expressions provide the ability to specify complex time combinations such as
+ * &quot;At 8:00am every Monday through Friday&quot; or &quot;At 1:30am every 
+ * last Friday of the month&quot;. 
+ * <P>
+ * Cron expressions are comprised of 6 required fields and one optional field
+ * separated by white space. The fields respectively are described as follows:
+ * 
+ * <table cellspacing="8">
+ * <tr>
+ * <th align="left">Field Name</th>

+ * <th align="left">Allowed Values</th>

+ * </table>
+ * <P>
+ * The '*' character is used to specify all values. For example, &quot;*&quot; 
+ * in the minute field means &quot;every minute&quot;.
+ * <P>
+ * The '?' character is allowed for the day-of-month and day-of-week fields. It
+ * is used to specify 'no specific value'. This is useful when you need to
+ * specify something in one of the two fileds, but not the other.
+ * <P>
+ * The '-' character is used to specify ranges For example &quot;10-12&quot; in
+ * the hour field means &quot;the hours 10, 11 and 12&quot;.
+ * <P>
+ * The ',' character is used to specify additional values. For example
+ * &quot;MON,WED,FRI&quot; in the day-of-week field means &quot;the days Monday,
+ * Wednesday, and Friday&quot;.
+ * <P>
+ * The '/' character is used to specify increments. For example &quot;0/15&quot;
+ * in the seconds field means &quot;the seconds 0, 15, 30, and 45&quot;. And 
+ * &quot;5/15&quot; in the seconds field means &quot;the seconds 5, 20, 35, and
+ * 50&quot;.  Specifying '*' before the  '/' is equivalent to specifying 0 is
+ * the value to start with. Essentially, for each field in the expression, there
+ * is a set of numbers that can be turned on or off. For seconds and minutes, 
+ * the numbers range from 0 to 59. For hours 0 to 23, for days of the month 0 to
+ * 31, and for months 1 to 12. The &quot;/&quot; character simply helps you turn
+ * on every &quot;nth&quot; value in the given set. Thus &quot;7/6&quot; in the
+ * month field only turns on month &quot;7&quot;, it does NOT mean every 6th 
+ * month, please note that subtlety.  
+ * <P>
+ * The 'L' character is allowed for the day-of-month and day-of-week fields.
+ * This character is short-hand for &quot;last&quot;, but it has different 
+ * meaning in each of the two fields. For example, the value &quot;L&quot; in 
+ * the day-of-month field means &quot;the last day of the month&quot; - day 31 
+ * for January, day 28 for February on non-leap years. If used in the 
+ * day-of-week field by itself, it simply means &quot;7&quot; or 
+ * &quot;SAT&quot;. But if used in the day-of-week field after another value, it
+ * means &quot;the last xxx day of the month&quot; - for example &quot;6L&quot;
+ * means &quot;the last friday of the month&quot;. When using the 'L' option, it
+ * is important not to specify lists, or ranges of values, as you'll get 
+ * confusing results.
+ * <P>
+ * The 'W' character is allowed for the day-of-month field.  This character 
+ * is used to specify the weekday (Monday-Friday) nearest the given day.  As an 
+ * example, if you were to specify &quot;15W&quot; as the value for the 
+ * day-of-month field, the meaning is: &quot;the nearest weekday to the 15th of
+ * the month&quot;. So if the 15th is a Saturday, the trigger will fire on 
+ * Friday the 14th. If the 15th is a Sunday, the trigger will fire on Monday the
+ * 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th. 
+ * However if you specify &quot;1W&quot; as the value for day-of-month, and the
+ * 1st is a Saturday, the trigger will fire on Monday the 3rd, as it will not 
+ * 'jump' over the boundary of a month's days.  The 'W' character can only be 
+ * specified when the day-of-month is a single day, not a range or list of days.
+ * <P>
+ * The 'L' and 'W' characters can also be combined for the day-of-month 
+ * expression to yield 'LW', which translates to &quot;last weekday of the 
+ * month&quot;.
+ * <P>
+ * The '#' character is allowed for the day-of-week field. This character is
+ * used to specify &quot;the nth&quot; XXX day of the month. For example, the 
+ * value of &quot;6#3&quot; in the day-of-week field means the third Friday of 
+ * the month (day 6 = Friday and &quot;#3&quot; = the 3rd one in the month). 
+ * Other examples: &quot;2#1&quot; = the first Monday of the month and 
+ * &quot;4#5&quot; = the fifth Wednesday of the month. Note that if you specify
+ * &quot;#5&quot; and there is not 5 of the given day-of-week in the month, then
+ * no firing will occur that month.
+ * <P>
+ * <!--The 'C' character is allowed for the day-of-month and day-of-week fields.
+ * This character is short-hand for "calendar". This means values are
+ * calculated against the associated calendar, if any. If no calendar is
+ * associated, then it is equivalent to having an all-inclusive calendar. A
+ * value of "5C" in the day-of-month field means "the first day included by the
+ * calendar on or after the 5th". A value of "1C" in the day-of-week field
+ * means "the first day included by the calendar on or after sunday".-->
+ * <P>
+ * The legal characters and the names of months and days of the week are not
+ * case sensitive.
+ * 
+ * <p>
+ * <b>NOTES:</b>
+ * <ul>
+ * <li>Support for specifying both a day-of-week and a day-of-month value is
+ * not complete (you'll need to use the '?' character in on of these fields).
+ * </li>
+ * </ul>

+ * before the check is done.

+ * the task before the check is done in the tearDown.

+ * An execution can only receive external triggers in case it is in 
+ * the active state.  
+ * 
+ * Nested executions can occur in case of scoped executions
+ * and in case of concurrent executions.  In both cases, only 
+ * leave executions in the execution hierarchy are active.
+ * 
+ * Executions are either locked or active.  So in any state which 
+ * is not active, the execution is locked and cannot accept external 
+ * signals.  Executions can be ended in 3 ways:
+ * 
+ *  1) with execution.end() : then the state will be set to 'ended'
+ *  2) with execution.cancel() : then the state will be set to 'cancelled'
+ *  3) with execution.end(String) : then the state will be set to the 
+ *     given state string.  An exception will be raised if the given 
+ *     state maches any of the known states.

+    <title>What is it</title>
+    <para>jBPM is an extensible and flexible process engine that can run 
+    as a standalone server or embedded in any Java application.
+    jBPM can run multiple process languages and it supports multiple 
+    execution modes.
+    </para>
+  </section>  
+
+  <section>
+    <title>Contents of this userguide</title>
+    <para>In this user guide, we'll describe the jPDL 
+    process language in persistent execution mode.  Persistent 
+    execution mode means that process definitions, process executions 
+    and process history is stored in a relational DB.  This is the common way 
+    of how jBPM is used. 
+    </para>
+    <para>This user guide explains the supported way on how to use jBPM.
+    The developers guide explains more advanced customization options that 
+    are not supported. 
+    </para>
+    <para>TODO ?Explain what is meant by supported? Shouldn't it be clear to user's that it is more
+    geared towards extenders? That they can use it but that there is no guarantee of infinite stability?

+  <section id="processdefinitionprocessinstanceandexecutions">
+    <title>Process definition, process instance and executions</title>
+    <para>A process definition is description of the steps in a procedure.
+    For example, an insurance company could have a <literal>loan</literal> 
+    process definition that describes the steps of how the company deals 
+    with loan requests.

+    </figure>
+    <para>One process instance represents one particular run of a process definition.
+    For example, the loan request of John Doe last Friday to finance his new boat 
+    is represented in one process instance of the loan process definition.
+    </para>
+    <para>A process instance contains all the runtime state.  The 
+    most prominent property is the pointer that keeps track of the current activity.
+    </para>

+      <mediaobject><imageobject><imagedata align="center" fileref="images/loan.process.instance.png"/></imageobject></mediaobject>
+    </figure>
+    <para>Suppose that wiring the money and archiving can be done in parallel.
+    Then the main process instance will have two child executions to keep 
+    track of the state like this:

+    </figure>
+    <para>More general, a process instance is the root of a tree of executions.
+    When a new process instance is started, the process instance is in fact the root 
+    execution scope.  Only leaf executions can be active.
+    </para>
+    <para>The motivation to work with a tree structure like this is that
+    this conceptually remains simple in the case where there is only one path 
+    of execution.  The services API doesn't need to make a functional difference 
+    between process instances and executions.  Therefore, the API has only 
+    one Execution type to refer to both <literal>ProcessInstance</literal>s and 
+    <literal>Execution</literal>s.

+    <programlisting>ProcessEngine processEngine = new Configuration()

+    from the default configuration file <literal>jbpm.cfg.xml</literal> which is 
+    expected in the root of the classpath.  If you want to specify another

+    <title>Deploying a process</title>
+    <para>The <literal>ProcessService</literal> groups all methods that access 
+    the repository of process definitions.
+    </para>
+    <para>A jPDL process file like e.g. <literal>order.jpdl.xml</literal> that is 
+    accessible as a resource on the classpath can be deployed programmatically with the 
+    <literal>ProcessService</literal> like this:
+    </para>
+    <programlisting>processService.createDeployment()
+    .addResource("order.jpdl.xml")
+    .deploy();</programlisting>
+    <para>Analogue to the <literal>addResource</literal> method above, the source of 
+    the processes definitions XML can be picked up from a file, url, string, 
+    input stream, zip or jar archive and a directory.
+    </para>
+    <para>A deployment works with a set of named resources and can potentially contain 
+    multiple process descriptions and multiple other artifact types.  The jPDL deployer 
+    will recognise process files based on the <literal>.jpdl.xml</literal> 
+    extension automatically.  For files not adhering to that naming 
+    convention, the type can be set programmatically to <literal>jpdl</literal>
+    with method <literal>setFileType("my-jpdl-process.someotherextension", "jpdl")</literal>
+    </para>
+    <para>During deployment, an <literal>id</literal> is assigned to the process 
+    definitions.  The <literal>id</literal> will have format 
+    <literal>{key}:{version}</literal>
+    </para>
+    <para>If <literal>key</literal> is not provided, it is generated automatically 
+    based on the name.  All non alpha numeric characters in the name will be replaced 
+    by underscores to generate the key.
+    </para>
+    <para>The same <literal>name</literal> can only be associated to one 
+    <literal>key</literal> and vice verca.
+    </para>
+    <para>If <literal>version</literal> is not provided, a <literal>version</literal> 
+    will be automatically be assigned.  For version 
+    assignment, the versions of all deployed process definitions with the same name will 
+    be taken into account.  The assigned <literal>version</literal> will be one higher 
+    then the highest <literal>version</literal> number of deployed process definitions 
+    with the same <literal>key</literal>.  If no process definitions with a similar
+    <literal>key</literal> have been deployed, version number 1 is assigned. 
+    </para>
+    <para>In this first example, we'll supply a name and nothing else.</para>

+      scope of all versions of a process definition.  Typically it is easy

+    <para>A process definition describes what must be done in terms of activities.
+    Each activity in a process is either to be performed by the process 
+    system or by an external participant.  When an activity is to be performed 
+    by an external participant, then the execution must wait until the 
+    external participant notifies the process system that the activity is 
+    completed.  So an execution is either executing or waiting on an external 
+    participant.  Typically, you'll see that the processes are mostly 
+    waiting for external participants.  Especially humans tend to be slow :-)
+    The time consumed by the process system between two wait states is 
+    typically very small.
+    </para>
+    <para>A <literal>state</literal> is the basic activity that represents

+    </para>
+    <para>When an execution is in a wait state, it can be given an external trigger 
+    with one of the signal methods.  The recommended way to reference an execution 
+    is by using the process definition and execution key.  In the next code snippet,
