I'm using JBPM 5.4, Jboss AS 7.1.1, Spring 3
The Knowledge Base it's been 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 )
{code}
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");
}
{code}
My Environment:
{code}
public Environment getEnvironment() {
if(environment == null) {
LOGGER.info("CREATING NEW ENVIRONMENT");
environment = KnowledgeBaseFactory.newEnvironment();
environment.set(EnvironmentName.ENTITY_MANAGER_FACTORY, getEntityManagerFactoryJbpm());
}
return environment;
}
{code}
How I register my handlers:
{code}
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);
}
{code}
Anyone have any insight? I already searched the whole community, but nothing helped.
