"Unable to run the business process using JBPM 5.4"

--------------------------------------------------------------
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 -

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?
