Now I want to get the list of the table that is not empty. I use this:

esbcomlog = session.createQuery("from EsbCommonlog").list();



the list result is of size 220 = size of the table but 200 null



Then i try this
Criteria c = session.createCriteria("model.EsbCommonlog");
List<EsbCommonlogId> cl= (List<EsbCommonlogId>) c.list();

same thing



any idea?

thanx a lot.
