EJB Timer still active even after the bean is undeployed !

nouredine13 Mar 3, 2009 10:01 AM

Hello,

i have the following problem:

I can not kill an ejb timer after the call unregisterTimer method, and the timer is still active even after the ejb is undeployed.

the source code of my bean is here under :

package com.test.timer;

import javax.annotation.PreDestroy;
import javax.annotation.Resource;
import javax.ejb.EJBException;
import javax.ejb.Local;
import javax.ejb.NoSuchObjectLocalException;
import javax.ejb.Remote;
import javax.ejb.SessionContext;
import javax.ejb.Stateless;
import javax.ejb.Timeout;
import javax.ejb.Timer;
import javax.ejb.TimerHandle;
import javax.ejb.TimerService;
import javax.ejb.TransactionAttribute;
import javax.ejb.TransactionAttributeType;
import javax.ejb.TransactionManagement;
import javax.ejb.TransactionManagementType;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import org.apache.log4j.Logger;




 @Local( ITimerManagerLocal.class)
 @Remote(ITimerManagerRemote.class)
 @TransactionManagement(TransactionManagementType.CONTAINER)
 @TransactionAttribute(TransactionAttributeType.SUPPORTS)
 @Stateless( name = "NotifyExpiration", mappedName="NotifyExpirationRemote")
 public class TimerManagerBean implements ITimerManagerLocal, ITimerManagerRemote {


 private static final Logger logger = Logger.getLogger ( "EXPIRATION_SERVICE");

 @Resource
 private SessionContext sessionContext;

 @Resource
 private TimerService timerService;

 //--------------------------------------------------------------------------
 // Methods
 //--------------------------------------------------------------------------
 @PreDestroy
 public void unregisterTimer() throws NamingException {

 logger.info( "NOTIFY TIMEOUT UNREGISTER");

 Context ctx = new InitialContext();

 try {
 TimerHandle handle = (TimerHandle) ctx.lookup( "TIMER_JNDI_NAME");
 ctx.unbind("TIMER_JNDI_NAME");
 if (handle != null){
 try {
 Timer expirationTimer = handle.getTimer();
 if (expirationTimer != null){
 expirationTimer.cancel();
 }
 } catch (NoSuchObjectLocalException e) {
 logger.warn( "UNABLE TO UNREGISTER TIME OUT", e);
 } catch (IllegalStateException e) {
 logger.warn( "UNABLE TO UNREGISTER TIME OUT", e);
 } catch (EJBException e) {
 logger.warn( "UNABLE TO UNREGISTER TIME OUT" , e);
 }
 }
 } catch (Throwable thre){
 logger.warn( "UNABLE TO UNREGISTER TIME OUT", thre);
 return;
 }
 }


 public void registerTimer() throws NamingException {
 unregisterTimer();
 int delai = 10 * 1000;
 Timer expirationTimer = createTimer( delai);
 Context ctx = new InitialContext();
 ctx.bind("TIMER_JNDI_NAME", expirationTimer.getHandle());
 if (logger.isInfoEnabled()){
 logger.info("TIMER REGISTERED " + expirationTimer.getNextTimeout().getTime());

 }
 }

 private Timer createTimer( int delai)
 {
 try {
 return sessionContext.getTimerService().createTimer(delai, delai, null);
 } catch( Throwable thr) {
 return timerService.createTimer (delai, delai, null);
 }
 }

 @Timeout
 //@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
 public void timedOut(Timer obj)
 {
 try {
 if (logger.isDebugEnabled()){
 logger.debug(
 String.format("TIMER WAKEUP at: " + System.currentTimeMillis()));

 }
 logger.debug("do something...");
 }catch (RuntimeException e) {
 logger.debug( "TIMER WAKEUP FAILS");
 }
 }


}

so first i register the timer by calling registerTimer() method, and i wont to kill it by calling unregisterTimer() method. but this does not work, and the timer remains active even after the bean is undeployed.

If somme one has an idea or workaround to solve this problem ?

Thank you so match.

Regard's.

but this does not work, and the timer remains active even after the bean is undeployed.

How did you verify this? Can you post the appropriate logs which show this behaviour?

I'm sure the timer is not killed because I see in the logs that the timer is still active.

i will post the log file in the afternoun.

Thank's.

Also please post the logs which show the undeployment itself, apart from the logs after the undeployment.

Hello,

- First I called the method registerTimer ().

- Secondly, I called the method unregisterTimer (), the method fails and the timer is not killed.

- Third, I undeploy my ear, and deploy it again, the portion of log file shows that the timer is still active:

Thank's a lot.

regard's.

5. Re: EJB Timer still active even after the bean is undeployed

Hi!

According to ejb-3.0 spec (page 88) in @PreDestroy method in stateless bean only following method are allowed:

- SessionContext methods: getBusinessObject, getEJBHome, getEJBLocalHome, getEJBObject, getEJBLocalObject,getTimerService, lookup
- JNDI access to java:comp/env
- EntityManagerFactory access

as you see 'TimerService and Timer methods' are not mentioned here, so you cannot cancel timer in PreDestroy method.

6. Re: EJB Timer still active even after the bean is undeployed

nouredine13 Mar 10, 2009 5:37 AM (in response to nouredine13)
i have found the solution :

I killed all timers associated with the current bean, for instance :

//to be sure that there is not previous timer still running on JBOSS Collection timersList = timerService.getTimers (); for (Object timer: timersList) { if (timer instanceof Timer) { log.debug ("Timer still running, kill it : "+timer); ((Timer)timer).cancel (); } }

thank you for your answer.

Regard's.
