We're running jboss-3.2.7 and trying to upgrade to Hibernate 3.1. I've followed the Hibernate3 Migration Guide, but ran into conflict with jboss's jboss-hibernate.sar which is Hibernate 2.x. Specifically I get a ClassCastException on deployment of my application's hibernate sars, no doubt because they're 3.0 and trying to load in concert with the 2.0 jboss/hibernate deployment.

I've seen mention of plans for jboss-3.2.x support for Hibernate 3.0 in these forums, but nothing that nails the problem. I expect what I need is a Hibernate 3.0 equivalent of the jboss-hibernate.sar under the deploy directory. In the absence of some blessed version, I'm considering 1) hand building my own, including modifying jboss code (not very enthusiastically) , 2) borrowing such a deployment from jboss-4.x, also not enthusiastic about this option.

Any suggestions/experience from others?
