Hibernate version: 3.2.2

Name and version of the database you are using: Firebird 2.0.3 (Windows)

Not sure the subject properly gets at what I'm trying to do, but it was the best I could come up with.

I have an entity, A, and a different entity, B. There is a bi-directional many-to-many mapping between them, with A in charge of the association.

I need to find all the A entities that have a B entity in their collection, but I need to do it with only B's ID, not an actual B. Any suggestions as to how to go about this?

Thanks,
Jamie
