Hi
Yes, I know that I already promissed to create a HowTo on the time
issue but I didn't got the time.
But for short there's the way (I assume that you are in the same JVM
as jBoss is running):
- Add a <MLET> tag to jBoss.conf loading "javax.management.timer.Timer"
- Get a reference to the MBeanServer. If you are in a MBean then you
get it for free (during pre or post registration) otherwise you have it
to get it from JNDI or through MBeanFactory.getMBeanServer() ).
- Get the ObjectInstance through the MBeanServer like:
Set lBeans = lBeanServer.queryMBeans(
new ObjectName( "DefaultDomain", "service", "timer" ),
null
);
if( !lBeans.isEmpty() ) {
ObjectInstance lTimerBean = (ObjectInstance)
lBeans.iterator().next();
- use addNotification() on the Timer to set what you are interested in:
lBeanServer.invoke( lTimerBean.getObjectName(), "addNotification",
new Object[] { <List of parameters see JavaDoc> },
new String[] { <List of parameters data type> }
);
- add yourself as a Notification Listener:
lBeanServer.addNotificationListener(
lTimerBean.getObjectName(), <your listener instance>
);
That's it.
