James, thanks a lot for your help below. i was actually able to try the list() method and it lists everything that's in my jndi.properties file. i think the reason is that my InitalContext in the first place does a 'lookup' in the jndi.properties file.
however, lets say my activemq broker is running and thru the jmx console i add a new topic on the fly - this new topic name will NOT be in my jndi.properties. however, yes - it does now exist on the broker. so to work in this scenario, i'm trying to get a list of destinations that are active directly from the broker. in interface Broker there is a method called getDestinations() - some of the classes that implement this interface, for example BrokerBroadcaster, RegionBroker, etc. "may help" me in doing what i want to do... but i'm not sure exactly how to use them... any ideas? class BrokerService also has a getDestinations() method. the problem i'm having is that when invoke the getBrokerName() method of class BrokerService, it returns a "null". because its a null i am not sure how to proceed further. on the other hand, when i invoke the getBrokerURL() method of class ActiveMQConnectionFactory - it does return the expected result: "tcp://localhost:61616 any further guidance from you on how i may accomplish my task with the above information (or any other which i may be missing) will be highly appreciated. Thanks!
