Hi, 

I'm trying to migrate my app to jbpm 5.3 with spring. First my files:


Beans:




       <jee:jndi-lookup id="JbpmDataSource" jndi-name="${jdbc.datasource.name}" />







JbpmTaskServiceImpl.java

       @PersistenceUnit
          private EntityManagerFactory emf;

           @Autowired
          private KnowledgeBase kbase; 

          @Autowired
          private TaskSessionSpringFactoryImpl taskSessionFactory; 

          private TaskServiceSession taskServiceSession;

        @PostConstruct
          private void initTaskServiceSession() {


                    Environment env = KnowledgeBaseFactory.newEnvironment();
                    env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
                    env.set(EnvironmentName.TRANSACTION_MANAGER,
                                        TransactionManagerServices.getTransactionManager());
                    env.set(EnvironmentName.TRANSACTION_SYNCHRONIZATION_REGISTRY,
                                        TransactionManagerServices
                                                            .getTransactionSynchronizationRegistry());
                    env.set(EnvironmentName.GLOBALS, new MapGlobalResolver());
                    env.set(EnvironmentName.OBJECT_MARSHALLING_STRATEGIES,
                                        new ObjectMarshallingStrategy[] {
                                                            new JPAPlaceholderResolverStrategy(env),
                                                            new SerializablePlaceholderResolverStrategy(
                                                                                ClassObjectMarshallingStrategyAcceptor.DEFAULT) });


                    this.taskServiceSession = this.taskSessionFactory
                                        .createTaskServiceSession();
                    // this.taskServiceSession = taskService.createSession();


                    StatefulKnowledgeSession ksession = JPAKnowledgeService
                                        .newStatefulKnowledgeSession(kbase, null, env);


                    CustomSyncWSHumanTaskHandler humanTaskHandler = new CustomSyncWSHumanTaskHandler(
                                        this, ksession);


                    humanTaskHandler.setLocal(true);


                    humanTaskHandler.connect();


                    ksession.getWorkItemManager().registerWorkItemHandler("Web Flow Task",
                                        humanTaskHandler);
                    ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
                                        humanTaskHandler);


                    CustomWebServiceTaskHandler serviceHandler = new CustomWebServiceTaskHandler(
                                        ksession);


                    ksession.getWorkItemManager().registerWorkItemHandler(
                                        "Web Service Task", serviceHandler);


                    new JPAWorkingMemoryDbLogger(ksession);
          }


When I try to start my server, I get javax.persistence.TransactionRequiredException: No local transaction to join. And when I debug, the ksession have a null WorkItemManager... don't know why.

Thanks for your help.
