two ejb modules with different persistence provider in one ear

[jdabrowski]

With JBoss7.1.0.Final is it possible to have two ejb modules in ear, one using hibernate:3 persistence provider and second using default (hibernate4) one?

When I try to do that I get:

Hibernate version is 3.5.5.Final.

I think that you are the first to try that.  Since the Hibernate:3 + Hibernate4 persistence providers share the provider class name, I don't think it will work very well.  Especially, in the latest AS7 nightly build, where both providers will be in the javax.persistence.Persistence provider list (Hibernate:3 only visible to your application).
