client id for topic connections.

[Suchitha Koneru (sukoneru)]

Hello Active Mq users , 
                   We use active mq broker 4.1.1 for communication
between two jvms. Topic publishers , non persistent delivery of messages
and  durable subscribers are  used. 
 
// The following is the code snippet for creating a durable subscriber 
 
    ActiveMQSession session;
   TopicConnection topicConn;
    Topic topic;
   TopicSubscriber subscriber ;
   String clientID;
 
 subscriber =   session.createDurableSubscriber(topic,
durableSusbscriptionName);
  topicConn.setClientID(clientID)'
 
 
//the code for  shut down of the subscriber is 
    subscriber.close();
    session.unsubscribe(durableSubscriptionName)
   session.close();
      topicConn.close();
 
Is the Client ID associated with  the topic connection removed when the
connection is closed ? If one of the JVM's is re started we should not
land into invalid client id exceptions. 
 
Please advise the correct approach to be followed.
 
thanks,
Suchitha.
