    Does JBPM 5.1 works with Websphare6.1

    sandeep kumar Newbie

      Does JBPM5.1 work with Websphare 6.1?

      I did changes in persistence.xml to use websphare transaction manager, but it could not work and giving excepion related to transaction.

       

      Regards

          We can't help much unless you ask more specific questions, provide exception logs, details of what you changed, etc.

            Hi Tihomir

                 Thanks for your reply. I debug the issue and found that the problem is due to creation of ksession using JPA. When I run the same code in J2SE environment by using Bitronix transaction manager, it works well. But when i ship it to Websphare using websphare transaction manager I am getting this exceptin.

            These my codes

            KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

            kbuilder.add(ResourceFactory.newClassPathResource("rvb-process.bpmn"), ResourceType.BPMN2);

            KnowledgeBase kbase = kbuilder.newKnowledgeBase(); EntityManagerFactory emf = Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" );

            Environment env = KnowledgeBaseFactory.newEnvironment();

            env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );

             

            env.set( EnvironmentName.GLOBALS, new MapGlobalResolver() );

             

            Properties properties = new Properties();

            properties.put("drools.processInstanceManagerFactory", "org.jbpm.persistence.processinstance.JPAProcessInstanceManagerFactory");

            properties.put("drools.processSignalManagerFactory", "org.jbpm.persistence.processinstance.JPASignalManagerFactory");

            TransactionManager tm =

            new WebSphereTransactionManagerLookup().getTransactionManager(properties);

            env.set( EnvironmentName.TRANSACTION_MANAGER, tm );

            KnowledgeSessionConfiguration config = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(properties);

            JPAKnowledgeService.newStatefulKnowledgeSession(kbase, config, env)
