Any help on this would be appreciated. I've got an object with a one-to-many relationship mapped as a Set (user.roles). Given a list of roles, how can I return the users with at least one matching element?

Thanks a lot!

The easiest would be to use the role ids like:
Code:
Query qry = session.createQuery("from User as u join u.roles as r where r.id in (:roleIds)");
qry.setParameterList("roleIds", roleIdList);
return qry.find();
