Thanks! That really helps me in putting the effort in the right direction. I think in my environment we fall under the second cateogory mentioned below - we are accessing remote broker. Also, in my JMX console window... under "org.apache.activemq" --> "localhost" --> "Broker" --> "Info" I can see the MBean Java Class = org.apache.activemq.broker.jmx.BrokerView. The BrokerView implements BrokerViewMBean. The problem that I am having now is that I don't know how access the BrokerView object? Am I missing something obviously simple here? Any guidance on this will be very helpful. Thanks!
