How to retrieve updated payload information from completed HumanTask

Question

after initiating the HumanTask , updating the payload object from java client api
payload information set into task object.
taskService.updateTaskOutcome(workflowContext, task, outcome) ;
after this call the HumanTask will be Completed.
Now i tried to get the Payload which was updated in earlier step.
Task task=taskQueryService.getTaskDetailsByNumber(workflowContext, taskNumber);
XMLElement payload =(XMLElement)task.getPayloadAsElement();
in the payload, it only contains payload which was at the time of humanTask initiation .
Can any one help me, how to retrieve the payload information after completing the HumanTask ?
Thanks in Advance

Answer 1

I think the below code can be used to update the payload in the HumanTask
IWorkflowServiceClient wfSvc=WorkflowServiceClientFactory.getWorkflowServiceClient(WorkflowServiceClientFactory.REMOTE_CLIENT);
          //instantiate the TaskQueryService Object
          ITaskQueryService taskQuerySvc=wfSvc.getTaskQueryService();
          //instantiate the TaskService Object. it has the UpdateOutcome method
          ITaskService taskSvc=wfSvc.getTaskService();
          final String password="jcooper";
          final int taskNumber=123;
          try {
               //get WorkflowContext
               IWorkflowContext context=taskQuerySvc.authenticate("jcooper",password.toCharArray(), "jazn");
               Task task=taskQuerySvc.getTaskDetailsByNumber(context, taskNumber);
               Element element=task.getPayloadAsElement();
               Element payloadNew=element.getOwnerDocument().createElementNS("http://xmlns.oracle.com/bpel/workflow/task", "payload");
               JAXBContext jaxbContext=JAXBContext.newInstance("object.path");
               Marshaller marshaller=jaxbContext.createMarshaller();
               //new Object() is your Object which you want to update in Process payload
               marshaller.marshal(new Object(), payloadNew);
               task.setPayloadAsElement(payloadNew);
               //update task payload
               taskSvc.updateTaskOutcome(context, task, "APPROVE");
          } catch (WorkflowException e) {
               e.printStackTrace();
          } catch (JAXBException e) {
               e.printStackTrace();
          } catch (StaleObjectException e) {
               e.printStackTrace();
