Hi - I'm on the 3.6.10 version of hibernate entitymanager/core.
In earlier versions I could add the hibernate-annotations to get hold of @OnDelete and get properly DDL generated with on cascade delete.

If I add hibernate-annotations to the application I get a bootup fail:
Caused by: java.lang.NoSuchMethodError: org/hibernate/cfg/AnnotationConfiguration.getPersisterClassProvider()Lorg/hibernate/persister/PersisterClassProvider;

And if I remove it the DDL will be generated without cascading delete (which is an error).

So - what to do?

Baah - my fault - sorry for the noise - the annotation had moved to the hibernate-core artifact - and I had a runtime scope.
Everything working like a charm now.
