Hi all,

I've been reading up on many-to-many associations on the web and in Hibernate in Action, but I couldn't find the answer to my problem.

I've got an Object of my own class Query, I would like to add some security to this object, so I've created a User object. Each query can have several users that can access it, and each user can have several queries it can run..

This is the part of the query mapping file:


When I create a Query Object, I fill the users-set with UserQuery objects, but when I save the query (session.saveOrUpdate(query)), I get an exception:



Is it possible to save a many-to-many on cascade, or should you do it manually.. if it's possible.. what am I doing wrong?

Thanks in advance!!
