On the contrary, the thing is that in multi-app environments, i.e. JBoss AS, people shouldn't fiddle with this cos IIRC, the JPA/Hibernate deployer makes sure that the region prefix has the correct information about the deployment.

So, better not touch it and let the integration layer do what's best at, integrate multiple apps in a single environment.
