Timer Service: Bean does not have timers in EJB3.1

Question

Actually, am migrating an application from EJB2.1 to EJB3.1. After changed the application I got an issue while calling getTimers() method.

I am using the Websphere server.

Here is my code:

@Stateless
@TransactionManagement(TransactionManagementType.BEAN)
public class TimedRequestBean implements TimedRequestLocal {    
    @Resource
    private SessionContext sessionContext;
    public void cancelTimers() {
            TimerService ts = this.sessionContext.getTimerService();
            Collection timers = ts.getTimers();
            Iterator it = timers.iterator();
            while (it.hasNext()) {
                Timer myTimer = (Timer)it.next();
                myTimer.cancel();
            }
       }
}

Log:

javax.ejb.EJBException: See nested exception; nested exception is: java.lang.IllegalStateException: Timer Service: Bean does not have timers: BeanId(LeadDeliverySystemEAR#timedrequest.jar#TimedRequestBean, null) java.lang.IllegalStateException: Timer Service: Bean does not have timers: BeanId(LeadDeliverySystemEAR#timedrequest.jar#TimedRequestBean, null) at com.ibm.ejs.container.BeanO.getTimers(BeanO.java:1733) at com.ford.it.request.async.TimedRequestBean.cancelTimers(TimedRequestBean.java:460)

Finally I got the solution. I have implement the TimedObject interface in my bean Its working fine. Here is my code.

@Stateless
@TransactionManagement(TransactionManagementType.BEAN)
public class TimedRequestBean implements TimedRequestLocal, TimedObject {    
    @Resource
    private SessionContext sessionContext;
    public void cancelTimers() {
            TimerService ts = this.sessionContext.getTimerService();
            Collection timers = ts.getTimers();
            Iterator it = timers.iterator();
            while (it.hasNext()) {
                Timer myTimer = (Timer)it.next();
                myTimer.cancel();
            }
       }
}
