To view the discussion, visit: https://community.jboss.org/message/719772#719772 -------------------------------------------------------------- Hi, I also have found that you must force to complete the WorkItem after completing a human task. A more detailed and a little bit cleaner version of Melih and Donald approach also works perfectly, even when the human task server is running on a separate thread or JVM, provided that the process engine JPA persistence is correctly configured and the original statefull knowledge session is restored upon start-up. Some boilerplate code intentionally omitted for the sake of simplicity: // If no previous statefull knowledge session exists public void createStatefullKnowledgeSession() {      //... create kbase, load process definitions, etc ...      EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa");      Environment env = KnowledgeBaseFactory.newEnvironment();      env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);      env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager());      ksessionStatefull = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env);      int sessionId = ksessionStatefull.getId();      // *** STORE sessionId SOMEWHERE PERSISTENTLY, to be able to      // recover this session later upon services restart } public void loadStatefullKnowledgeSession() {        //... create kbase, load process definitions, etc ...        EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa");      Environment env = KnowledgeBaseFactory.newEnvironment();      env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);      env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager());        // *** RECOVER sessionId FROM PERSISTENT STORAGE      // and use it here to recover persisted process engine state      ksessionStatefull = JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, kbase, null, env);   } public void complete(long taskId, String userName)     throws Exception {               // ... create the TaskClient (client), and connect it to the task server ...               // first mark the task as completed on the task server             taskOperationHandler = new BlockingTaskOperationResponseHandler();             client.complete(taskId, userName, null, taskOperationHandler);             taskOperationHandler.waitTillDone(1000);               // then retrieve the task to extract the workItemId, where the process instance is waiting             BlockingGetTaskResponseHandler responseHandler = new BlockingGetTaskResponseHandler();             client.getTask(taskId, responseHandler);             responseHandler.waitTillDone(1000);               Task task = responseHandler.getTask();               // force completition of the workItem associated with the task, on which the process instance is waiting             final Map<String, Object> results = new HashMap<String, Object>();             ksessionStatefull.getWorkItemManager().completeWorkItem(task.getTaskData().getWorkItemId(), results); } Hope this will be useful to anyone, best regards! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/719772#719772] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
