Hi Thomas, I'm sorry i thought you were in Beijing.

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?

Thanks and Best Regards!
