Is their any major difference with respect to Performance in using Criteria vs HQL based queries?

I am considering Criteria based queries for my project as I faced issues to get HQL working fine.

I posted this already in forum but didn't get any hint so far. When I used HQL I am getting SessionFactory as null sometimes not always. In no place I am clearing sessionFactory. When I start jboss server sessionfactory gets created successfully.

Jboss : 4.0.3 / Postgres 8.2/ Hibernate 3.0.1 RC1

Thanks
Sun

Sundar,
Yes. I feel execution time for criteria queries is costly than HQL. caz hibernate engine internally converts criteria queries into HQL.

I don't thing problem in creating session factory when executing HQL.
