When I try to call "removeNotification" on the Timer mbean, I get the following:

javax.management.ReflectionException: The operation with name removeNotification could not be found

In my mbean, I do the following:

getServer().invoke(mTimer, "removeNotification", new Object[] { timer }, new String[] { Integer.TYPE.getName() } );

where
mTimer = new ObjectName("DefaultDomain", "service", "timer"),
and timer is an Integer that I get from addNotification.

What am I doing wrong? I'm using JBoss-2.4.4.

Thanks,
