Hibernate allows you to validate your configuration against a database with the SchemaValidator object. Its takes one input parameter, a Configuration.

In a JPA environment (Hibernate 3.1.1, Annotations 3.1B8, EntityManager 3.1B6) how can I retrieve the Configuration so that I can pass it into the validator? My configuration is specified with Annotations.

I know how to retrieve a SessionFactory from an EntityManagerFactory, or a Session from an EntityManager, but can't figure out how to get to the underlying hibernate configuration. I looked at the Hibernate Tools, and they don't support schema validation.

Thanks for any help.

hibernate.hbm2ddl.auto validate does it,
otherwise I'll have to offer a possibility to get a Configuration out of an EJB3Configuration

Thanks as always Emmanuel, not just for your help on the forums, but for the JPA implementation itself. Your suggestion was just what I needed.

By putting
into my persistence.xml file, I now get a boot time error from my JPA program pointing out the details of any skews between the code and the schema.

validate on server boot up is fine. but if i can have it as an ant task or as a mave pojo it woild be great since it will save my server boot up time.
