ganesh r [https://community.jboss.org/people/ganesh0902] created the discussion "Unable to run the business process using JBPM 5.4" To view the discussion, visit: https://community.jboss.org/message/777659#777659 -------------------------------------------------------------- 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 Exception in thread "main" org.jbpm.workflow.instance.WorkflowRuntimeException: [com.sample.bpmn.hello:1 - User Task:4] -- Could not connect task client: on ip: 127.0.0.1 - port: 5445 at org.jbpm.workflow.instance.impl.NodeInstanceImpl.trigger(NodeInstanceImpl.java:132) at org.jbpm.workflow.instance.impl.NodeInstanceImpl.triggerNodeInstance(NodeInstanceImpl.java:279) at org.jbpm.workflow.instance.impl.NodeInstanceImpl.triggerCompleted(NodeInstanceImpl.java:238) at org.jbpm.workflow.instance.node.ActionNodeInstance.triggerCompleted(ActionNodeInstance.java:55) at org.jbpm.workflow.instance.node.ActionNodeInstance.internalTrigger(ActionNodeInstance.java:51) at org.jbpm.workflow.instance.impl.NodeInstanceImpl.trigger(NodeInstanceImpl.java:126) at org.jbpm.workflow.instance.impl.NodeInstanceImpl.triggerNodeInstance(NodeInstanceImpl.java:279) at org.jbpm.workflow.instance.impl.NodeInstanceImpl.triggerCompleted(NodeInstanceImpl.java:238) at org.jbpm.workflow.instance.node.StartNodeInstance.triggerCompleted(StartNodeInstance.java:49) at org.jbpm.workflow.instance.node.StartNodeInstance.internalTrigger(StartNodeInstance.java:41) at org.jbpm.workflow.instance.impl.NodeInstanceImpl.trigger(NodeInstanceImpl.java:126) at org.jbpm.ruleflow.instance.RuleFlowProcessInstance.internalStart(RuleFlowProcessInstance.java:35) at org.jbpm.process.instance.impl.ProcessInstanceImpl.start(ProcessInstanceImpl.java:194) at org.jbpm.workflow.instance.impl.WorkflowProcessInstanceImpl.start(WorkflowProcessInstanceImpl.java:309) at org.jbpm.process.instance.ProcessRuntimeImpl.startProcessInstance(ProcessRuntimeImpl.java:170) at org.jbpm.process.instance.ProcessRuntimeImpl.startProcess(ProcessRuntimeImpl.java:140) at org.drools.common.AbstractWorkingMemory.startProcess(AbstractWorkingMemory.java:1098) at org.drools.impl.StatefulKnowledgeSessionImpl.startProcess(StatefulKnowledgeSessionImpl.java:320) at com.sample.ProcessMain.main(ProcessMain.java:35) Caused by: java.lang.IllegalArgumentException: Could not connect task client: on ip: 127.0.0.1 - port: 5445 at org.jbpm.process.workitem.wsht.GenericHTWorkItemHandler.connect(GenericHTWorkItemHandler.java:158) at org.jbpm.process.workitem.wsht.GenericHTWorkItemHandler.executeWorkItem(GenericHTWorkItemHandler.java:180) at org.drools.process.instance.impl.DefaultWorkItemManager.internalExecuteWorkItem(DefaultWorkItemManager.java:70) at org.jbpm.workflow.instance.node.WorkItemNodeInstance.internalTrigger(WorkItemNodeInstance.java:107) at org.jbpm.workflow.instance.impl.NodeInstanceImpl.trigger(NodeInstanceImpl.java:126) ... 18 more Before running the business process I have started h2, jboss and task service using ant start.demo Do I'm missing anything here? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/777659#777659] Start a new discussion in jBPM Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
