I found deleting PO with Hibernate to be a big nuisance. If I want to delete a child, it looks like I am always violating some kind of constraints. If I have a unidirectional association from a parent to its child and got hold of the child, it looks like there is no way of deleting it without introducing a bidirectional association and then removing the child from the parent.

Did I get something wrong? Can anybody shed some light on this?

Thanks in advance.
