No, IBM has no such RAR. They do not provide a JCA/JMS RAR for WebSphereMQ that I know of. You are more than welcome to use our JMC/JCA adapter with a few exceptions. What I want to know about ESB's integration strategy in terms of tranasctional resources in general. We should be using JCA wherever possible. If we don't right now that's fine, but moving forward we should coordinate this type of effort between the teams.
