The org.hibernate:ogm module should depend on Hibernate 4 (org.hibernate:main) and Hibernate 4 should depend on OGM. We should either create a blog update to explain this or as previously discussed on this thread, document the changes needed. http://pastie.org/4891854 is my current persistence.xml that I'm testing with. I had to set jboss.as.jpa.adapterModule to org.jboss.as.jpa.hibernate:4, so that we would use the Hibernate 4 integration code with OGM. I also had to set jboss.as.jpa.classtransformer to false so that we wouldn't try to create the EntityManagerFactory too soon (should probably verify if that is still needed). I sometimes hear that question (why don't you just use the JPA spec bootstrapping). However, we are allowed by the JPA specification, to pass a map of integration properties when calling the PersistenceProvider.createContainerEntityManagerFactory(PersistenceUnitInfo, Map integrationProperties) call. Sometimes, the persistence providers include enough version specific application server integration code, so that app servers find that its good enough to just call the JPA spec invocation but in practice this breaks when the app servers change too much. For AS7, I created persistence provider adapters that (optionally) contain the extra integration code that is not handled by the JPA specification. For AS 8.0, I want to change the relationship between the persistence provider adapters and providers to be less tightly coupled (its currently a 1-1) but they make developing JPA applications for AS7 easier for the developer (fewer properties have to be passed in). I created a git branch locally but haven't started the actual doc changes yet. Scott
