    help major problem

    richard bradwell Newbie

      Hi,

      I have a major problem that I am finding hard to debug. I am using version 3.2.2 of jbpm on weblogic 9.2. I have an stateless session bean that is using container managed persistence. The problem I am seeing is that when I make the transition to an end state in the graph it is falling over. Transition to any other state is ok. The stack trace I get is given below. Essentally it's saying

      Caused by: org.hibernate.SessionException: Session is closed!

      I have remote debugged right through my own code and the jbpm code. It's only once all the code has executed and the enterprise bean tries to commit the transaction that it happens. What baffles me is why it is only the case for the end states. Apologies that I haven't provided much info but it's difficult to know what would be relevant. I'm totally lost. I'm hoping someone will have a few hypthesis that I can test out. By the way I had my code working on an earlier version of jbpm!

      cheers

      Richard.
