i'm using session beans and hibernate jpa.as far as i know if we use hibernate.cfg.xml
and persistence.xml are one of them overrides the other,anyway.
As you said i didn't use packages.i will use it. i used hibernate annotations but
didn't put any@Entity and the other tags.Could you please how to use hibernate entity
manager in jboss.
my aim to use jsf in jboss and o/r mapping with hibernate.
