jBPM 4.4 How do I force a process instance to end

Kevin Moodley Newbie

How do I force a process instance to end?


I have a basic flow with a fork and a join (see attached image).  If one of the forks fails the process instance never ends because the join is never reached.


What is the easiest way to find and force the Process Instance to end in this situation.


Thanks for your help.

    By the way  I tried using


    processEngine.getExecutionService().endProcessInstance(instanceId, ProcessInstance.STATE_ENDED);


    but this threw a null-pointer exception:

    Hi Kevin,


    Please provide your jpdl.xml and testcase,  it will help us to understand this problem easily,  Thank you very much.

    try this:executionService.deleteProcessInstance(processInstanceId);

    I am basically using a modified version of your concurrency example (attached) but I make one of the forks take an ERROR transition and then try to force the process instance to end via :




    This works fine unless I have an <on event="end"> on the jPDL. In this case an event is fired, after the process ends,   to handle the on end event. But this results in a null pointer exception because there are no more activities or transitions at this point. UserCodeReference.getProcessDefinition returns null.


    My basic problem is : How do I end a Process Instance if the join is not reached due to an error transition from one of the nodes feeding the join.

    Hi Kevin,


    I think this is a bug. I've modified the source of the ReflectUtil class to handle the null case and it works. I've filed an issue in the jBoss JIRA: http://jira.jboss.org/browse/JBPM-2932
