    Injection of bean in Timer

    jcarlos_andia

      Hi.

      I have an Action handler associated to the event NODE_ENTER of a state. The first time it executes (when the token enters the node) a timer is created. The next "n" times (which is fired by the timer and not by the event) the method tries to look for a Stateful session bean in context. This is the code:

      public class MyActionHandler implements ActionHandler{
      
       private static final long serialVersionUID = -7574831777028763706L;
      
       public void execute(ExecutionContext context) throws Exception{
      
       if(context.getTimer()==null){
       System.out.println("ADDING TIMER ...");
       Calendar cal=Calendar.getInstance();
       BusinessCalendar bc=new BusinessCalendar();
       Duration duration=new Duration("20 seconds");
       Date dueDate=bc.add(cal.getTime(), duration);
      
       Timer myTimer=new Timer();
       myTimer.setName("[TIMER] "+context.getEventSource().getName());
       myTimer.setDueDate(dueDate);
       myTimer.setRepeat("20 seconds");
       myTimer.setRetries(3);
      
       myTimer.setAction(context.getAction());
      
       context.setTimer(myTimer);
      
       context.getJbpmContext().getServices().getSchedulerService().createTimer(myTimer);
       }else{
       System.out.println("EXECUTING ...");
      System.out.println("CommonUtil="+Component.getInstance("commonUtil"));
      
       }
       }
      


      It fails when it tries to retrieve the bean from the context. The log:

      14:43:25,612 INFO [STDOUT] EXECUTING ...

      It seems that when the timer if fired it doesn't "look" in the context where all beans are. Any idea of how can I solve this?. Or a way to inject seam components within a timer context? Thanks in advance.
