[jboss-user] [Management, JMX/JBoss] - Timer problem when using jconsole

I had a weird problem in deploying my application under JBOSS-4.0.5, caused
by a failure in finding an instance of Timer.

Here is an overview of what I was doing:
1) my application contains an MBean in which I inject a dependency on Timer using the following code:

  | 	private static final String TIMER_SERVICE_NAME = "DefaultDomain:service=timer";
  | 
  | 	private static final long TIME_GRANULARITY = Timer.ONE_MINUTE;
  | 
  | 	private final MBeanServer server = MBeanServerLocator.locateJBoss();
  | 	
  | 	/**
  | 	 * need to put timer-service.xml in the deploy directory to make it work
  | 	 * 
  | 	 * @uml.associationEnd
  | 	 */
  | 	@Depends(TIMER_SERVICE_NAME)
  | 	private TimerMBean timer;
  | 
  | 	@Depends(TIMER_SERVICE_NAME)
  | 	private ObjectName timerName;
  | 
  | 
 2) later on in the application I add to server some Notifications in order to call another function of the MBean
	when I receive a Notification from the Timer

3) I deploy also a timer-service.xml in JBoss:

<server>
  | 
  |   <!-- ==================================================================== -->
  |   <!-- JMX Timer MBean                                                      -->
  |   <!-- ==================================================================== -->
  | 
  |    <mbean code="javax.management.timer.Timer" name="DefaultDomain:service=timer"/>
  | 
  | </server>
  | 
  | 

Now, the code was working, and I was able to see from the jmx-console my MBean

Then I decided I want to use jconsole from Sun java distribution, so I read some wiki pages in JBoss
web site, and I added to $JBOSS_HOME/bin/run.conf the following line:

JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote"

When I tried to deploy again my application, after restarting JBoss with the previous options, I got the
following error when JBoss tried deploying my application:

Then I decided to check from jboss jmx-console if the Timer was there, and from the web page I can see it...(with the correct name: DefaultDomain:service=timer)

I'm curious to understand the reason of the problem, if there is some expert that is willing to explain it ;-)

Thanks in advance,
Andrea
