There is the example in the HiA book for implementing HibernateUtil (Listing 8.3) and using the doFilter (listing 8.4) and then there is the example in CaveatEmptor.

I'm assuming the CaveatEmptor example is more robust?

Can the book example be used in production?

Any suggestions/comments on which one to go with?

Thanks.

So the note in http://hibernate.org/42.html...stating that Every other HibernateUtil is obsolete for Hibernate 3.1. pertains to the HIA thread-local example (listing 8.3) too?

Does enabling the thread-bound strategy (see below) in your Hibernate configuration solve the same problem the thread-local HIA HibernateUtil was solving?

Every means all.

Hi Christian,

Can you advise if can I use the HibernateUtil.java in caveatemptor-0.9.5 which implements filter and use JPA EntityManager to replace the Hibernate Session?

Basically I was using the HibernateUtil.java in caveatemptor-0.9.5, I can use it fine with Hibernate 3.2.cr2. When I discover more, I came across JPA and understand Hibernate actually implements JPA. So, I would like to know how should I write my HibernateUtil.java in order to use JPA that implements through Hibernate.

Hope you can advise me so that I can kick start on this.

Please advise.
Thank you.

HibernateUtil is for Hibernate. Use the version on http://hibernate.org/42.html

For JPA you can use a JPAUtil class that holds the EntityManagerFactory, just like HibernateUtil holds the SessionFactory. That is the only purpose of such a *Util class, don't do anything else in there.

Ignore CaveatEmptor alpha stuff if you don't know the basics, it's not supposed to be understood without a book.
