In my case,in fact i want to get the vars's value when i get a task by userid. And these values are passed when i start a processinstance. i set & get values all in myself application. no using the jbpm console.  Also no using marshall and unmarshall. *Set values when start process:* Map<String,Object> params = new HashMap<String,Object>();    params.put("sales", c.getCreateby());    params.put("contractno", c.getContractno());    params.put("details", c.getDetails());    params.put("amount", c.getAmount());    params.put(role.getRole(), leader.getName());    params.put("accoptor", list.get(0).getName()); getSession().startProcess(definitionId, processVars); *Get values when get a task by userid:* List<TaskSummary> t = sTaskService.getTasksAssignedAsTaskInitiator(idRef, "en-UK");    if(null != t && t.size() > 0){         for(TaskSummary ts : t){      Object obj = getTaskContentInput(ts);      Map<?, ?> map = (Map<?, ?>) obj;                 for (Map.Entry<?, ?> entry : map.entrySet()) {                      System.out.println(entry.getKey() + " = " + entry.getValue());                 }      tasks.add(new TaskRef(ts.getId(), ts.getProcessInstanceId() + "", ts.getProcessId(),        ts.getName(), ts.getCreatedBy().getId(), ts.getStatus() == Status.Suspended, ts.getStatus() != Status.Suspended));     }        }  *And the getTaskContentInput method as blow:* public Object getTaskContentInput(TaskSummary taskSum) {          BlockingGetTaskResponseHandler handlerT = new BlockingGetTaskResponseHandler();          client.getTask(taskSum.getId(), handlerT);          Task task2 = handlerT.getTask();          TaskData taskData = task2.getTaskData();          BlockingGetContentResponseHandler handlerC = new BlockingGetContentResponseHandler();          client.getContent(taskData.getDocumentContentId(), handlerC);          Content content = handlerC.getContent();          ByteArrayInputStream bais = new ByteArrayInputStream(                          content.getContent());          try {                  ObjectInputStream is = new ObjectInputStream(bais);                  Object obj = null;                  while ((obj = is.readObject()) != null) {                          System.out.println("OBJECT: " + obj);                          return obj;                  }          } catch (Exception e) {                  System.err.print("There was an error reading task input...");                  e.printStackTrace();                               return null;          }          return null; } Is My way right or wrong? Would you pls give some advice?
