* Company's web application uses JAAS login. Whenever I call my EJB's methods (scheduleJob and cancelJob ) that contains timerService.createTimer() or Timer.cancel(), I always get kicked out of web app as if I wasn't logged in, and have to relogin again.
* I do see the job is indeed scheduled after I relogin.
* Once a job is scheduled, it runs fine.
* there is no error msg/stacktrace from the console when submit new job or cancel.
* However, get list of timers (getScheduledJobs) works fine, without kicking me out.

What should I do so I can use Timer service functions without losing authentication?

I'm using JBoss 4.0.2.

public class TimedCommandHandlerServiceBean implements SessionBean, TimedObject {

 public void scheduleJob(ScheduledJob job, Date initialTime){
 TimerService timerService = ctx.getTimerService();
 timerService.createTimer(initialTime,job);
 }

 public void cancelJob(ScheduledJob aJob){
 TimerService timerService = ctx.getTimerService();
 Collection timers = timerService.getTimers();

 for(Iterator iter = timers.iterator(); iter.hasNext();){
 Timer timer = (Timer)iter.next();
 ScheduledJob job = (ScheduledJob)timer.getInfo();
 if(job.getName().equals(aJob.getName())){
 timer.cancel();
 break;
 }
 }
 }

 public Collection getScheduledJobs(){
 TimerService timerService = ctx.getTimerService();
 Collection timers = timerService.getTimers();

 Collection result = new ArrayList();
 for(Iterator iter = timers.iterator(); iter.hasNext();){
 Timer timer = (Timer)iter.next();
 ScheduledJob job = (ScheduledJob)timer.getInfo();
 result.add(job);
 }
 return result;
 }
