Hello all,

I have the following Table structure:

USER{

user_id int PK
session_info varchar

}

PROFILE{

user_id int PK/FK
...

}

I have been trying to use one-to-one mappings, at first uni-directional from the User object, so that my Profile object didn't have a reference to the User object. But since I wanted Hibernate to handle the keys, I had to make it bi-directional. My problem now is I can't seem to have a NULL Profile in the User object.

Do I need to use a many-to-one to achieve this?

This seems like a very simple mapping, but the most logical mapping (one-to-one) doesn't seem to fit.

And advice would be greatly appreciated.

Thanks,
Patrick

Ok, I think I have this working the way I want it to.

I was getting some odd "Null reference" things because Spring was Auto-Wiring my User object and giving it a Profile object that of course didn't have a reference back to the User object. I stop the Auto-Wiring and things appear to be working the way I want.

Well, except for the Profile object still needing the reference to User, but I can live with that.

Thanks,
Patrick
