title: How do I detect if a JMS instance is up in a jboss cluster
body: <p>I have a clustered jboss environment and some JMS queues in it. 
  I only want one instance of the Queue to run at one time.
  I am new to JMS API. Can I write some code to detect JMS instances running in the cluster to achieve this?
  I have seen code to find if a queue exists via JNDi lookup, but I think it only looks up the server's JVM and not the entire cluster. Please advise.</p>
  
  <p>Thanks!
