[jboss-dev-forums] [EJB 3.0 Development] - HornetQ JCA Adapter question

[ataylor]

Guys,

HornetQ has its own RA adapter for MDB's and we have a question regarding the spec and the ejb3 implementation you may be able to answer.

This is regarding section 12.5.6 of the JCA spec.

Originally we used Option B and used the beforeDelivery/afterDelivery methods on MessageEndpoint to control transaction demarcation etc.

We have recently changed this however to use Option A, we did this so we could have more control over the transactions so we could add things like local tx optimization, transaction batching etc. According to the spec with option A you don't call beforeDelivery/afterDelivery, you can see this clearly in figure  12-7 that this doesn't occur.

The problem is that because we don't call these methods the Thread Context Classloader no longer gets set, so the question is this! Is the spec slightly ambiguous here, should we always call before/afterDelivery to do this. I would have thought that if we didn't call these then the MessageEndpoint proxy would still set the TCL before calling the MDB onMessage method.

Any input would be appreciated!
