Lester,

One small problem comes up, related to this one.

As you can imagine, I call the function, desribed in the previous psot from a testfile.
All works fine now, except

If I remove the System.out.println(ret.get(0).toString());

Than the old error comes back
(org.hibernate.LazyInitializationException: could not initialize proxy - the owning Session was closed)

Even when I put a
Hibernate.initialize((Archetyped) ret.get(0));
instead, it makes no difference.

Do you have any idea?

For testing purposes, I can proceed with working, but I do not like code which I don't understand

Yes, that's right! When you call System.out.println(ret.get(0).toString()) inside doInHibernate(Session session) and, respectivly, inside session you initialize ArctypeID property-proxy (you must see additional select in console or log). To make this work without this line, you must call Hibernate.initialize(((Archetyped) ret.get(0)).getArctypeID()), not Hibernate.initialize((Archetyped) ret.get(0)), inside doInHibernate(Session session) method because you want to initialize property(proxy) of the Arctyped object, not the Arctyped object itself. Or you can use HQL query with left join fetch as i write before.

Thanks, Lester, you have been a great help
