"Re: InvocationTargetException when creating StatefulKnowledgeSession" To view the discussion, visit: https://community.jboss.org/message/722867#722867 -------------------------------------------------------------- jtaManager is the JBoss TransactionManager (arjuna). It's injected, as the class where the above code lives is actually an MBean. I've made some - limited - progress with this. It appears that the JPAKnowledgeService doesn't like to participate in an existing JTA transaction. By marking the method with @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED), I am able to get a session created within a UserTransaction. The code now looks like this: UserTransaction txn = retrieveTransaction(); txn.begin(); kSession = JPAKnowledgeService.newStatefulKnowledgeSession( kBase, null, env ); kSession.getWorkItemManager().registerWorkItemHandler("ValidationService", new ValidationTaskWorkItemHandler()); kSession.getWorkItemManager().registerWorkItemHandler("SubscriptionEventUpdateService", new SubscriptionHistoryWorkItemHandler()); kSession.getWorkItemManager().registerWorkItemHandler("ImmunizationService", new JMSWorkItemHandler()); kSession.getWorkItemManager().registerWorkItemHandler("SchoolFormService", new JMSWorkItemHandler()); kSession.getWorkItemManager().registerWorkItemHandler("LegacySubscriptionService", new JMSWorkItemHandler()); I'm not thrilled about having to deal with UserTransaction, though. Isn't this supposed to support standard managed transactions? Is there something additional I need to provide to the env for it to participate normally? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/722867#722867] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
