Hi Philip,
I'd just like to illustrate what I meant with an example. Why don't you try
it this way and tell me if it works for you:
| <process-definition name="sample-event-listener">
| <start-state>
| <transition to="event-listener"/>
| </start-state>
|
| <state name="event-listener">
| <event type="node-enter">
| <action class="..." />
| </event>
| <transition name="end-process" to="end-state"/>
| </state>
|
| <end-state name="end-state"/>
|
| </process-definition>
action handler class:
| public void execute(ExecutionContext ctx) throws Exception {
| long processid = ctx.getProcessInstance().getId();
|
| //since this is asynchronous, it will pass this immediately
| //and return handle to the main context
| AsyncEventListenerThread th = new AsyncEventListenerThread( id );
| th.start();
| }
the sample listener thread
| public class AsyncEventListenerThread extends Thread {
| long processid = processid;
|
| public AsyncEventListenerThread( long processid ) {
| this.processid = processid;
| }
|
| public void run() {
| //place your event listenter here. A JMS client would be good here
| //after event arrives, call a new JbpmSession, locate the process,
| //signal it and save and don't forget to close the jbpm context.
| }
| }
While you're at it, try also reading on asynchronous continuations. Maybe they
have something there that's already done for this job. I have not yet read on
that, let me know. Good luck.
Regards,
Elmo
