Start by creating a class @Name("org.jboss.seam.persistence.persistenceProvider") | @Scope(ScopeType.STATELESS) | @BypassInterceptors | @Install(classDependencies="something.TopLink.Specific", genericDependencies=ManagedPersistenceContext.class) | public class TopLinkPersistenceProvider extends PersistenceProvider { | | } This will then take precedence over HibernatePeristenceProvider (as discussed elsewhere it is still on your cp due to using an old Hibernate Annotations for validator support), and will just use the basic EJB3 PeristenceProvider.
