Ok now I am completely lost. Please someone help me out. I can't figure this out. I migrated from Hibernate 2 to Hibernate 3. I am trying to do a simple update and it is not working. I can save a new data, but I can not update or delete. I was using Hibernate Synchronizer but after fighting with it for two days and posting for help everywhere I got no where. So for simplicity I now tried using HibernateUtil and even then it does not work. The following is Types.hbm.xml
public class HibernateUtil {
private static Log log = LogFactory.getLog(HibernateUtil.class);

The following is a simple function that makes the update using HibernateUtil inside of my EJB:
I am using JBoss and I am packaging Hibernate stuff inside a HAR file.
I am not getting any error messages and the update is not happening at the Database layer. Does anybody see what might be the problem?
