You have to use JMX to access it and enable JMX in activemq.

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!

IMO, using BrokerService.getDestinations() will only work when you are
using embedded brokers. I.e. you are deploying the JMS broker inside
your app and you have access to the BrokerService object.
If you want to access a remote broker (i.e. if you run it via
./activemq), you need to use JMX and call the getTopics, getQueues, etc
of the BrokerViewMBean.
Hope that helps.

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!

Hi,
I am trying to write a debug tool where as a user, I do not know the
topicNames that exist. Normally, if I knew the topic name, I could just
do
this:
myContext.lookup(jndiName)
where jndiName is the topicName
Is there a way I can pass in an argument, or a wildcard argument that
will
look up all the topicNames that exist? Or is it possible that there is
an
all different way to do this?
Any help will be greatly appreciated.
Thanks!
