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. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/767007#767007] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
