[JBoss jBPM] - Don't see running process in JBPM
by DeanDeen
Hi,
I am working on test project with JBoss jBPM, SEAM on JBoss 4.2.3 Server using ORACLE DB.
Everything is working just fine, except this...
I deploy my application (which include jBPM preces definition) on server and run it via Firefox. My application works just fine as well as process in it.
BUT
When I go to check it in jbpm-console, I don't see nothing until I restart server. After restart I can see process.
What I am searching for is how to see (in jbpm-console) what is happening in my application (with my process) in real-time.
Assume that I am running my application and at some point in process execution I open jbpm-console. I would like so see process image and where exactly my process is at.
Thanks for any suggestion...
Dejan

[JBoss jBPM] - custom events / executionContext
by gchanteb
Hi all,
I'm trying to implement custom events. It works, but i have some questions:
I made a test with this process definition:
<process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="process8">
|
| <start-state name="start-state">
| <transition to="state1" name="to state1"/>
| </start-state>
|
| <state name="state1">
| <event type="node-enter">
| <action class="package.Action1"/>
| <script>
| System.out.println("node-enter!");
| </script>
| </event>
| <event type="custom-event">
| <action class="package.Action2"/>
| </event>
| <transition to="end-state" name="to end-state"/>
| </state>
|
| <end-state name="end-state"/>
|
| </process-definition>
With Action1:
public void execute(ExecutionContext executionContext) throws Exception
| {
| executionContext.getToken().getNode().fireEvent("custom-event", executionContext);
| }
And Action2:
public void execute(ExecutionContext executionContext) throws Exception
| {
| System.out.println("custom-event!");
| }
I start and signal the process with jbpm-console, it's ok.
But, first question:
If i change in my processdefinition.xml
<event type="custom-event">
| <action class="package.Action2"/>
| </event>
to
<event type="custom-event">
| <script>
| System.out.println("custom-event!");
| </script>
| </event>
I have an exception... :
anonymous wrote : Error signalling token: An exception of type "org.jbpm.JbpmException" was thrown. The message is: couldn't get value for file 'classes/java/lang/bsh.class'
Question 1- Why ? My System.out.println("node-enter!"); into node-enter!
My second question is:
Question 2 - I would like to start my custom-event into an EJB. I would like to know how to recover the "executionContext" in my code?
I made this test which doesn't work:
public void launchCustomEvent(String processName, long idProcess)
| {
| System.out.println("Launch custom event for "+processName+" / "+idProcess);
|
| jbpmContext = JbpmConfiguration.getInstance().createJbpmContext();
| ProcessInstance processInstance = jbpmContext.getProcessInstance(idProcess);
| ExecutionContext executionContext = new ExecutionContext(processInstance.getRootToken());
| processInstance.getRootToken().getNode().fireEvent("custom-event", executionContext);
| }
Thx.

[JBoss jBPM] - Re: Fetching Task Variable Instances (Early Loading)
by bradsdavis
Yeah, my suggestion here is the following.
First, I dont think this is as efficient as it should be. However, this is my suggestion at the most efficient result.
Create a DTO that includes the values you want in the grid. Then do a HQL query to fetch the task instance. The key is to make the variable local to the task instance so that it can be pulled in a eager fashion.
So, when you create your task, just add a controller that copies the value from the process instance to the task. That is equivalent to creating a variable locally on the task instance.
So, then you need to fetch the variable eagerly.
| "select task from org.jbpm.taskmgmt.exe.TaskInstance task fetch all properties left join fetch task.variableInstances varInstance"
|
When you are populating your DTO from your TaskInstance objects gathered in the HQL query, make sure you say "getVariableLocally("variableName") rather than the getVariable method. That is crucial.

[JBoss jBPM] - Re: jPDL: global event handlers
by bradsdavis
I am not sure of an official global event handler. I dont believe there is a way to do that, but here is one possible solution otherwise.
One option would be to write a log handler that executes on the different logs to send events. Most of the event types are logged, so you could get at the same data.
| <!-- A : org.jbpm.graph.log.ActionLog -->
| <!-- B : org.jbpm.context.log.ByteArrayUpdateLog -->
| <!-- C : org.jbpm.logging.log.CompositeLog -->
| <!-- D : org.jbpm.context.log.VariableDeleteLog -->
| <!-- E : org.jbpm.context.log.DateUpdateLog -->
| <!-- F : org.jbpm.context.log.HibernateStringUpdateLog -->
| <!-- G : org.jbpm.context.log.LongUpdateLog -->
| <!-- H : org.jbpm.context.log.HibernateLongUpdateLog -->
| <!-- I : org.jbpm.graph.log.ProcessInstanceCreateLog -->
| <!-- L : org.jbpm.context.log.DoubleUpdateLog -->
| <!-- M : org.jbpm.logging.log.MessageLog -->
| <!-- N : org.jbpm.graph.log.NodeLog -->
| <!-- O : org.jbpm.graph.log.TokenCreateLog -->
| <!-- P : org.jbpm.logging.log.ProcessLog -->
| <!-- R : org.jbpm.context.log.VariableCreateLog -->
| <!-- S : org.jbpm.graph.log.SignalLog -->
| <!-- T : org.jbpm.graph.log.TransitionLog -->
| <!-- U : org.jbpm.context.log.StringUpdateLog -->
| <!-- V : org.jbpm.context.log.VariableLog -->
| <!-- W : org.jbpm.context.log.VariableUpdateLog -->
| <!-- X : org.jbpm.graph.log.ProcessInstanceEndLog -->
| <!-- Y : org.jbpm.graph.log.TokenEndLog -->
| <!-- Z : org.jbpm.graph.log.ProcessStateLog -->
| <!-- 0 : org.jbpm.taskmgmt.log.TaskLog -->
| <!-- 1 : org.jbpm.taskmgmt.log.TaskCreateLog -->
| <!-- 2 : org.jbpm.taskmgmt.log.TaskAssignLog -->
| <!-- 3 : org.jbpm.taskmgmt.log.TaskEndLog -->
| <!-- 4 : org.jbpm.taskmgmt.log.SwimlaneLog -->
| <!-- 5 : org.jbpm.taskmgmt.log.SwimlaneCreateLog -->
| <!-- 6 : org.jbpm.taskmgmt.log.SwimlaneAssignLog -->
|
In the jbpm configuration, then just configure in your logger.
|
| <service name="logging">
| <factory>
| <bean class="you.logger.Class"></bean>
| </factory>
| </service>
