Hibernate version: 1.2

Problem Statement:

I'm stuck with the following scenario:

I have one parent with a primary key. Now parent's Primary Key is mapped to two Child objects and is also their Primary Key.

Hibernate provides a way to map one-to-one between two objects. In that case if I create a "Child" object then hibernate will automatically create a "Parent" object by using Parent key.

But the problem is with one "Parent" and two "Child", parent and both children must have same ID and must always be created in single transaction.

_____________
| Parent
|------------------
| pid (PK)
| text
|_____________


_____________
| Child1
|------------------
| pid (FK + PK)
| textC1
|_____________


_____________
| Child2
|------------------
| pid (FK + PK)
| textC2
|_____________

Thanking in advance for your wise replies

Maybe I misunderstand you but... In an one-to-one relationship you cannot have a parent with two/many children. You need an one-to-many relationship.
