Topic connection/clientID

[tcarter]

I am posting messages to a topic on a remote server using a TopicConnection with a specific clientID.

If the connection is lost (f.e. if the client system crashes), when I try to recreate the connection i get the following error:

This loggedOnClientIds is already registered !

This happens at TopicConnection.setClientID()

It seems that the JBoss MQ server is not aware that the client is dead.

Any ideas ?

Hi

There is no way the JBossMQ server could detect that a client is gone (the network could be temporary down or under heavy load). So a client ID cannot be release when the client crashes.
Also the spec. expects that when a client ID is already specified (by JBossMQ) you cannot change it. So I would suggest that you expect that a setClientID() fails and use another client ID instead.

Have fun - Andy
