Ok,
Class A can have many Class B.
Class B can have many Class A

Class A {
List<B> bs;
}

Class B {
List<A> as;
}

now I want to select some A classes that have a set of B classes in their list of B classes.
I.e. give me all A that have the B's with b.id=3, b.id=4, b.id=5 (all of them, not just one or two)
In Criteria form.

Could somebody help??
