[jboss-user] [jBPM] - Re: JTA Problem with multiple sessions

Gareth Edwards [https://community.jboss.org/people/garethed] created the discussion "Re: JTA Problem with multiple sessions" To view the discussion, visit: https://community.jboss.org/message/795772#795772 -------------------------------------------------------------- I am now ksession.addEventListener(new DefaultProcessEventListener(){   @Override public void afterProcessCompleted(ProcessCompletedEvent event){                                                   System.out.println("Disposing of " + event.getProcessInstance().getProcessName() + "!"); ksession.execute(new CMTDisposeCommand());                                         }                               }); I am creating a session and running an instance of a work-flow in it and then completing the workflow and disposing the session. I then create another session and another work-flow instance in the new session. This does not throw an error after completing the first work-flow on first session but now throws the exception when completing the next session of the next work-flow. 17:04:28,939 INFO  [stdout] (http--0.0.0.0-8080-2) WorkflowProcessInstance1 [processId=TrakCel.DataTest,state=1] 17:04:28,939 INFO  [stdout] (http--0.0.0.0-8080-2) Workflow Instance Variables 17:04:28,939 INFO  [stdout] (http--0.0.0.0-8080-2) agent:krisv 17:04:28,939 INFO  [stdout] (http--0.0.0.0-8080-2) test_id:TZ001A0001 17:04:56,464 INFO  [stdout] (Thread-75) Test is incorrect 17:04:56,465 INFO  [stdout] (Thread-75) trakzone_id:TZ001A0001 17:04:56,465 INFO  [stdout] (Thread-75) scanned_test_idTZ001A0001A 17:04:56,475 INFO  [stdout] (Thread-75) Disposing of DataTest! *At this point the fiest session has been disposed with no errors.* *A new session and work-flow instance is started* 17:09:53,795 INFO  [stdout] (http--0.0.0.0-8080-3) WorkflowProcessInstance3 [processId=Package1.DataTest,state=1] 17:09:53,796 INFO  [stdout] (http--0.0.0.0-8080-3) Workflow Instance Variables 17:09:53,796 INFO  [stdout] (http--0.0.0.0-8080-3) agent:krisv 17:09:53,796 INFO  [stdout] (http--0.0.0.0-8080-3) test_id:TZ001A0001 17:10:15,571 ERROR [org.drools.persistence.SingleSessionCommandService] (Thread-75) Could not commit session: java.lang.IllegalStateException: Illegal method call.
