[jboss-user] [JBoss jBPM] - Re: how to retrieve task instance/process instances in a spe

[yxyang]

Is the following code the correct way to retrieve the taskinstances for the specific tasknode name and task name?
 

  | 	private java.util.List getTaskInstance(String tasknodename, String taskname) throws Exception {
  | 		log.debug("getTaskInstance() is called");
  | 		log.debug("" + ctx.getCallerPrincipal().getName());
  | 		JbpmConfiguration config = null;
  | 		JbpmContext jbpmContext = null;
  | 		java.util.List list = null;
  | 		java.util.List list2 = new ArrayList();
  | 		try {
  | 			InitialContext ic = new InitialContext();
  | 			config = (JbpmConfiguration) ic
  | 					.lookup("java:/jbpm/JbpmConfiguration");
  | 			jbpmContext = config.createJbpmContext();
  | 			list = jbpmContext.getTaskMgmtSession().findPooledTaskInstances(ctx.getCallerPrincipal().getName());
  | 			for(Iterator iter=list.iterator();iter.hasNext();){
  | 				TaskInstance taskinstance =(TaskInstance) iter.next();
  | 				Task task =  taskinstance.getTask();
  | 				if(task.getName()!=null &&task.getName().equals(taskname) && task.getTaskNode().getName().equals(tasknodename)){
  | 					list2.add(taskinstance);
  | 				}
  | 			}
  | 			log.debug("return task instance set size ="+list2.size());
  | 		} finally {
  | 			if (jbpmContext != null)
  | 				jbpmContext.close();
  | 		}
  | 		return list2;
  | 	}
