[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.
