      I'm using JBPM 5.4, Jboss AS 7.1.1, Spring 3

       

      The Knowledge Base is being kept in another server.

       

      This is how I start my HornetQTaskServer:

      (Do I really need to start it? I've been trying to connect to the one that's supposed to come with jBPM. But, in that case, even though I can start the process, not a single task is persisted. I can only complete the process if I set the AsyncHornetQHTWorkItemHandler IP to localhost and start the HornetQ locally  )

       

           try{
                  TaskService taskService = new TaskService(getEntityManagerFactoryJbpm(), SystemEventListenerFactory.getSystemEventListener());
                  HornetQTaskServer server = new HornetQTaskServer(taskService, "localhost", 5445);
                  if(!server.isRunning()) {
                      Thread thread = new Thread(server);
                      thread.start();
                  }
              } catch(Exception e) {
                  LOGGER.warn("HornetQ Task Server já iniciado");
           }
      

       

      My Environment:

       

          public Environment getEnvironment() {
      
              if(environment == null) {
                  LOGGER.info("CREATING NEW ENVIRONMENT");
      
                  environment = KnowledgeBaseFactory.newEnvironment();
                  environment.set(EnvironmentName.ENTITY_MANAGER_FACTORY, getEntityManagerFactoryJbpm());
              }
              return environment;
          }
      

       

      How I register my handlers:

       

      public static void registerHandlers(StatefulKnowledgeSession kSession) {
      
              LOGGER.info("REGISTERING HANDLERS...");
      
              final EmailHandler emailHandler = new EmailHandler();
              final OrcamentoHandler orcamentoHandler = new OrcamentoHandler();
              final MudarStatusHandler mudarStatusHandler = new MudarStatusHandler();
      
              kSession.getWorkItemManager().registerWorkItemHandler("notificacao_lider", emailHandler);
              kSession.getWorkItemManager().registerWorkItemHandler("notificacao_negocio", emailHandler);
              kSession.getWorkItemManager().registerWorkItemHandler("notificacao_responsavel", emailHandler);
              kSession.getWorkItemManager().registerWorkItemHandler("modulo_orcamento", orcamentoHandler);
              kSession.getWorkItemManager().registerWorkItemHandler("muda_status", mudarStatusHandler);
      
              TaskClient client = new TaskClient(new HornetQTaskClientConnector(UUID.randomUUID().toString(), new HornetQTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));
              TaskManager taskManager = new TaskManager();
      
              AsyncHornetQHTWorkItemHandler htHandler = new AsyncHornetQHTWorkItemHandler(taskClient, kSession, true);
              htHandler.setPort(5445);
              htHandler.connect();
              kSession.getWorkItemManager().registerWorkItemHandler("Human Task", htHandler);
        }
      

       

      Anyone have any insight? I've already searched the whole community, but nothing helped.
