development environment: I am using NetBeans IDE to code. And I created my hibernate classes using the wizard from netBeans.
my server: jbossesb-server-4.4.GA Here is my hibernate.cfg: | <?xml version="1.0" encoding="UTF-8"?> | <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
