What is the JNDI name?

Here is an alternative (at least it seems to work for mee):
1. Ad listeners:
MBeanServer server = (MBeanServer) MBeanServerFactory.
findMBeanServer(null).iterator().next();
server.addNotificationListener(new ObjectName("Timer:service=Timer"),
listener,
filter,
o);
2. Add stuff to time:
timer = (TimerMBean)MBeanProxy.create(TimerMBean.class,"Timer:service=Timer");
timer.addNotification("test", "testing",
null, new java.util.Date(new java.util.Date().
getTime() +Timer.ONE_MINUTE )
);
With MLET set to:
<MLET CODE = "javax.management.timer.Timer" ARCHIVE="jmxri.jar" NAME="Timer:serv
ice=Timer" CODEBASE="../../lib/">
</MLET>
