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=3D"urn:jbpm.org:jpdl-3.2" name=3D"process8">
  | =

  | 	<start-state name=3D"start-state">
  | 		<transition to=3D"state1" name=3D"to state1"/>
  | 	</start-state>
  | =

  | 	<state name=3D"state1">
  | 		<event type=3D"node-enter">
  | 			<action class=3D"package.Action1"/>
  | 			<script>
  | 				System.out.println("node-enter!");
  | 			</script>
  | 		</event>
  | 		<event type=3D"custom-event">
  | 			<action class=3D"package.Action2"/>
  | 		</event>
  | 		<transition to=3D"end-state" name=3D"to end-state"/>
  | 	</state>
  | 	=

  | 	<end-state name=3D"end-state"/>
  | =

  | </process-definition>

With Action1:

	public void execute(ExecutionContext executionContext) throws Exception =

  | 	{
  | 		executionContext.getToken().getNode().fireEvent("custom-event", execu=
tionContext);
  | 	}

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=3D"custom-event">
  | 			<action class=3D"package.Action2"/>
  | 		</event>

to

		<event type=3D"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.Jb=
pmException" was thrown. The message is: couldn't get value for file 'class=
es/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 lik=
e 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+" / "+idPro=
cess);
  | 		=

  | 		jbpmContext =3D JbpmConfiguration.getInstance().createJbpmContext();
  | 		ProcessInstance processInstance =3D jbpmContext.getProcessInstance(id=
Process);
  | 		ExecutionContext executionContext =3D new ExecutionContext(processIns=
tance.getRootToken());
  | 		processInstance.getRootToken().getNode().fireEvent("custom-event", ex=
ecutionContext);
  | 	}

Thx.
