I have Entity1 and Entity2.
Entity1 have ref (One To One) on Entity2.
If i remove Enity2, i recive exception "ConstraintViolationException".
How i can remove Entity2 without:

Code:
...
Entity1.setEntity2(null);
em.merge(Entity1.);
em.remove(Entity2);
...

Thanx.

Couple things you can try.
i) Setup cascade on the Entity2 so that when you delete Entity2, corresponding entity1's are also deleted
ii) Setup Entity1 to have constrained="false" so that Entity1 need not have a mapping Entity2
