hibernate configuration / hibernate.hbm2ddl customize per application

Hi,

I'm in a situation where a database schema is shared by multiple applications. Some tables like User, Role, Orgs are used by all the applications. I want to setup hibernate configuration is those multiple applications in such a way that each of those applications just updates, or creates tables just related to it but not modify the global tables like User, Role, Orgs etc.

I couldn't come across any kind of annotation either.

Thanks for your ideas and solutions.
