I don't think it's needed to create a new class for this. Anyway, A ConnectionFactory will have to play with multiple delegates anyway. The best way to achive this is by having these delegates on the factory/replicated. Tim wrote : What do you mean by HAConnection, I am not aware of this term in JBoss Messaging Do you expect any JMS Connection Factory being able to round robbin with other servers? What about local connections? I think the user would have to choose if he wants a ConnectionFactory with HA features or not. This is just a matter of decide the use case.
