Assuming I have the following:

A* <-----> *B

and C has also has a many-to-many relationship to the association of A and B.

In my situation, C is dependent on A and B. From a relational perspective, I have the following two associative tables:

Table AB with a_id, b_id and table ABC with a_id, b_id and c_id. In table ABC, a_id and b_id are foreign keys that reference primary key a_id and b_id in table AB. Also, the primary key for table ABC is composite: a_id, b_id and c_id.

How do I map that in hibernate?

It even has its own section in the doco :)

http://www.hibernate.org/hib_docs/v3/reference/en/html/collections.html#collections-ternary

I was aware of the ternary section in the Hibernate doc but it was not too clear to me. Can you shed some light on it? Please use my scenario above to demonstrate how the mapping could be done.

Thanks
