Merge question

dkalna Mar 19, 2007 9:44 AM

Hi everybody,

may be simple question, but anyway:

I have "1 to n" relationship between A and B objects.
I get ma A from EntityManager, I call getBs() which
give me a Collection of Bs. Now I remove one B from
Collection (iterator.remove()) and call merge on A.

I would like to see that B I have removed in code will be
deleted from DB. Is this right or completely wrong?

Thanks a lot
Dalibor

Hi,

This has been discussed quite a few times before. See:

http://www.jboss.org/index.html?module=bb&op=viewtopic&t=78245

In summary, you must remove the B entity from the collection within A, and invoke em.remove(b) also.

The other alternative is to use a Hibernate specific annotation.
