The 2 examples are equivalent. The 2nd was the initial syntax, the 1st was a more generic extension that allowed the plugin-in of arbitrary filter factorys. I've provided already 4 filter factories that all work by 'enabling' what you want to receive. It wouldn't be very hard to extend those or write your own filter factory that works by instead 'disabling' what you don't want to receive. However, when it comes to the notifications emitted by the MBeanServerDelegate mbean, there is little point in disabling those 2 notifications types, because those are the only notifications this mbean produces. If you don't want to receive them, simply remove this mbean from the subscription list. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3980755#...
