--------------------------------------------------------------
I have downloaded latest JBPM 5.4 final full installer. After installing in my local machine, developed a business process with human task, start event -> user task -> end event.
To run the business process I have used the following code,

public static final void main(String[] args) throws Exception {
  // load up the knowledge base
  //startUp();
  KnowledgeBase kbase = readKnowledgeBase();
  StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
  HornetQHTWorkItemHandler humanTaskHandler = new HornetQHTWorkItemHandler(
    ksession);
  humanTaskHandler.setIpAddress("127.0.0.1");
  humanTaskHandler.setPort(5445);
  ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
    humanTaskHandler);
  Map<String, Object> params = new HashMap<String, Object>();
  params.put("title", "ESS");
  params.put("businessKey", "ESS-Key");
  // start a new process instance
  ksession.startProcess("com.sample.bpmn.hello",params);
 }
 private static KnowledgeBase readKnowledgeBase() throws Exception {
  KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
  kbuilder.add(ResourceFactory.newClassPathResource("sample.bpmn"), ResourceType.BPMN2);
  return kbuilder.newKnowledgeBase();
 }

But it is throwing the following exception,

0    21/11 03:07:38,030[main] ERROR service.hornetq.HornetQTaskClientConnector.connect  - Unable to connect to server using configuration org-hornetq-core-remoting-impl-netty-NettyConnectorFactory?port=5445&host=127-0-0-1

Before running the business process I have started h2, jboss and task service using ant start.demo

Do I'm missing anything here?
