Looks good to me. Just really have question about where this is going to be used in the code. If I understood you correctly one will be able to specify a concrete impl of an ActivationAdapter in the listener configuration element as a property. Will this class be used in the JmsListenerMapper? Could you provide an example just so I can visualize it?
