[jboss-user] [JBoss Messaging] - Re: Different Message id for each listener

Hello Assaf, I am still having trouble understanding your scenario:

  | 1) Producer sends Message A. 
  | 2) BEFORE Message A is recieved, some Connection failure occurs on the Listeners side. Note that the client does NOT crash, it's just a 'small' connection problem.
  | 3) JBM is trying to recover the Listeners Connection failure.

I'm not sure I understand what you mean by "JBM is trying to recover...".

Are you using a clustered connection? If so, JBM will attempt to failover to a new server if it detects the connection is lost.

Maybe you have coded your own exception listener and reconnect logic?

  | 5) JBM manages to recover the Connection failure (as to your question, remember that there is no need to Recreate the listeners because they never crashed in the first place).

Not sure what you mean by "JBM manages to recover..."

No redelivery mechanism should kick in unless you have coded your own exception listener and have implemented some retry logic.

Order should never be lost.
