Environment:
JBossAS 4.0.3SP1, default server
Sun JDK 1.4.2_10
Windows XP Sp2

I am trying to use the javax.management.timer.Timer class found in jboss-j2ee.jar. The Timer object reports that it is active, but I do not get any notifications. However, as soon as I point JAVA_HOME to Sun JDK 1.5.x, everything works just fine. I imagine it has to do with the Timer object having moved to the J2SE in that version.

I've read some old posts about having to start up a timer mbean using a timer-service.xml file. So, I created one and put it in the default/deploy/ directory and restarted the server. It didn't output any messages about picking up the file and my code still doesn't work.

What am I doing wrong?

Here's my timer-service.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<server>
 <mbean
 code="javax.management.timer.Timer"
 name="jboss:service=Timer" />
</server>

And here's my sample web application. I do get the "starting up" and "shutting down" messages, but not "timer fired".

import java.util.Date;

import javax.management.Notification;
import javax.management.NotificationListener;
import javax.management.timer.Timer;
import javax.servlet.http.HttpServlet;
import org.apache.log4j.Logger;

public class StartupServlet extends HttpServlet implements NotificationListener
{
 private static final long serialVersionUID = 1L;

 private static final Logger LOG = Logger.getLogger(StartupServlet.class);

 private Timer timer;

 public void init()
 {
 LOG.info("starting up");

 timer = new Timer();

 long interval = 5000; // milliseconds

 Date timerTriggerAt = new Date(System.currentTimeMillis() + interval);
 timer.addNotification(null, null, null, timerTriggerAt, interval);

 // Register this class as a listener
 timer.addNotificationListener(this, null, null);

 // Now start it.
 timer.start();
 }

 public void destroy()
 {
 LOG.info("shutting down");
 timer.removeAllNotifications();
 timer.stop();
 }

 public void handleNotification(Notification arg0, Object arg1)
 {
 LOG.info("timer fired");
 }
}
