Question

I am new to EJB 3 . I use the following code to start endless EJB 3 timer
then deploying it on JBOSS 4.2.3

@Stateless
public class SimpleBean  implements SimpleBeanRemote,TimerService  {

@Resource
TimerService timerService;
private Timer timer ;
@Timeout
public void timeout(Timer timer) {
    System.out.println("Hello EJB");

 }
}

then calling it

  timer = timerService.createTimer(10,  5000, null);

It works well. I created a client class that calls a method that creates the timer and a method that is called when the timer times out.

I forget to call cancel
then it does not stop .redeploy with cancel call never stop it. restart Jboss 4.2.3 never stop it. How I can stop EJB timer ?
Thanks for helping.

Answer 1

Put the stop() method into your bean and call it with your timer name as a parameter. It will iterate over all timers and will stop your timer.

public void stop(String timerName) {
    for(Object obj : timerService.getTimers()) {
        Timer t = (Timer)obj;
        if (t.getInfo().equals(timerName)) {
            t.cancel();
        }
    }
}
