According to the JMS 1.1 spec in section 6.3 towards the end: anonymous wrote : All JMS providers must be able to run JMS applications that dynamically create | and delete durable subscriptions. Some JMS providers may, in addition, | provide facilities to administratively configure durable subscriptions. If a | durable subscription has been administratively configured, it is valid for it to | silently override the subscription specified by the client. Shouldn't JbossMQ make sure that a call to topicSession.createDurableSubscriber(topic,subname) does not override what may have been setup in JMS_USERS? Or does this problem arise because the JMS_USERS approach to adding a subscription is trully not an "administered" way of dealing with a topic?
