JNDI, hibernate.cfg.xml, SessionFactory

Hello forum, I'm using Hibernate Tools in order to generate POJO classes, mapping classes and DAO's classes. Hibernate Tools generates me these files correctly. However I have taken several days how I can assemple all in J2EE web application structure.

The main problem is Hibernate Tools generates me DAO's files as this form -->

Code:

public class DAO {

   private static final Log log = LogFactory.getLog(StatusDAO.class);

   private final SessionFactory sessionFactory = getSessionFactory();

   protected SessionFactory getSessionFactory() {
      try {
         return (SessionFactory) new InitialContext()
               .lookup("SessionFactory");   <<<<--------------
      } catch (Exception e) {
         log.error("Could not locate SessionFactory in JNDI", e);
         throw new IllegalStateException(
               "Could not locate SessionFactory in JNDI");
      }
   }

   public void persist(Status transientInstance) {
      log.debug("persisting Status instance");
      try {
         sessionFactory.getCurrentSession().persist(transientInstance);

...

I don't know how do I use it? Concretly, I don't know how do I write hibernate.cfg.xml file in order to use JNDI, because getSessionFactory function uses ---- nitialContext().lookup("SessionFactory") ---- So, when I use a DAO, it finds one sessionFactory at tomcat (or others) resources, but I don't how do I configure it.

My definitive question is: How do I integrate DAO classes to use JNDI properties correctly?

Thanks for all.

the dao generation is not as optimal as i would like it to be.

but you can customize the templates to generate the code you would like to have in the getSessionFactory code...

How I can modify these templates? Does any tutorial exist?

Thanks

Mmm, I don't know how I can integrate this pacth to my Hibernate Tools. What Would I have to make to integrate this pacth in my HibernateTools?

Thanks max.
