i did some exploratory testing around this issue when diagnosing problems i=
 had with Durable Subscriptions.

ActiveMQ (5.3.0) appears to set aClient ID for the first Connection returne=
d from a ConnectionFactory, but not on subsequent Connections. The ID is co=
nstructed from the broker ID, i believe.

But you can call Connection.setClientID(String) to set it yourself, before =
calling Connection.CreateDurableConnectionConsumer().

Hi all,

   From the
http://activemq.apache.org/how-do-durable-queues-and-topics-work.html
http://activemq.apache.org/how-do-durable-queues-and-topics-work.html
   I want create a durable topic subscriber but at the consumer, I receive
some error "You cannot create a durable subscriber without specifying a
unique clientID on a Connection"
   At the consumer, my code fragment:
   ------------------------
   Topic topic =3D consumer.getSession().createTopic("STOCKS." + stock);
   TopicSubscriber consumer =3D
consumer.getSession().createDurableSubscriber(topic,"myDurable1");
   consumer.setMessageListener(new Listener());
   ------------------------

   Can show me some code fragments to create durable topic ?

   Thanks.
