Hibernate version: 2.1.x
Code between sessionFactory.openSession() and session.close():
Code:
I have 2 POJOs
1- Principal
2- Role
1-Init Principal POJO
1b- session.save(Principal);
2- Set principal to Role POJO
2b- session.save(Role)
I'm wondering how the many-to-one mapping works?
When I run my code, the PrincipalId column gets inserted into the Role table instead of the Principal. If I use ref-property, then I get the expected result. Just trying to understand what the dif is?
Thanks
