Hi,

I have a complex object with many n-n relation like this :

Code:

class A {
  List<B> listB;
  List<C> listC;
}

class B {
  List<D> listD;
}
class C {
  E e;
}
// Classes D and E are POJO without any relation.

How can I retrieve from the database an object 'A' fully loaded (with all the relations (listB, listC) and subrelations (listD) ...) in order to work with him in detached state. What is it the best solution to minimize the number of query executed ?

Note: I can not use the fetch mode Eager.

Thanks,

Julien
