Then what is the difference between: <mbean name="JMImplementation:type=MBeanServerDelegate"> | <filter factory="NotificationFilterSupportFactory"> | <enable type="JMX.mbean.registered"/> | <enable type="JMX.mbean.unregistered"/> | </filter> | </mbean> and: <mbean name="JMImplementation:type=MBeanServerDelegate"> | <notification type="jMX.mbean.registered"/> | <notification type="jMX.mbean.unregistered"/> | </mbean> If they are the same the how would I filter out a specific notification type? I am tring to NOT to receive bean registeration messages. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3980716#...
