jBPM is not aware of the current Hibernate session. It merely creates a new one if none is set in the jbpmContext. The session returned by: sessionFactory.getCurrentSession() differs from the one in jbpmContext.getSession() unless you call jbpmContext.setSession(sessionFactory.getCurrentSession()) before you do any persistent operation with the jbpmContext. Otherwise, the jbpmContext opens a separate Hibernate session. In your case it seems the current session remains open, while the jbpm-mantained session has already been closed. Note that when you inject an external session (with jbpmContext.setSession()) jBPM no longer closes the session for you. This is definitely what you want in a managed environment. Hibernate takes care of closing the session when the JTA transaction completes. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3972683#...
