I want to have following mapping: class X { int A; intB;} class Y{ X objct; int C} so the objct (of class X) is a composite of class Y, and both of objects (composite and owner) are in the same table. Is it possible to make such a mapping in TopLink? Thanks for every helpful answer. -- Piotr Bloch CS @ PUT Poland Back to top simon.martinelli@gmail.co Guest Posted: Mon Oct 30, 2006 9:45 pm    Post subject: Re: Oracle TopLink + composite mapping Hi, Yes that's possible. Map X as Aggregate Mapping. If you now map Y as "normal" Class Mapping you can choose the attributes of X to map to the database.
