Oh sorry, I should have said, the app must be JPA-compliant / portable.

Subject: maintaining bi-directional relationships
This is a design question really, sorry it's a little OT.
I assume I have responsibility for maintaining parent - child
relationships reflected by the parent.getChildren collection and
child.getParent entity at the point where the change occurs.
Is there a good pattern to implement changes to both the children
collection on the parent and the parent entity on the child?
One approach: setting field-access on the entity mapping, and adding
code to the setters with some sort of mechanism to stop infinite
looping.
