Hibernate and Neo4j cross store

Hi,

i am using hibernate with a relational database right now.

I want to add Neo4j to my persistence layer and to use spring data with cross store.

Is this possibly with hibernate? I saw some examples but they used the JPA entitymanager and I am using
the HibernateSessionFactory so when i annotate some fields with @RelateTo i get HibernateMappingExceptions because of an unknown type. So hibernate doesn't ignore this fields.

Thanks.

Is there a hibernate annotation to ignore fields? Can you add that to those fields?

Yes, I can annotate them with "@Transient". With this annotation hibernate ignores this fields, but neo4j doesn't persist them.
I think I need to pass a valid EntityManagerFactory to the neo4j configuration.

Maybe there is a way to get the JPA EntityManagerFactory from the HibernateSession?
