Thanks Alex! That did puzzle me for long before I hit your solution.

This was really helpful! I spent about 2 hours looking at my config files looking for something and took HibernateUtil for granted, what a huge mistake! Thanks a lot Alex :)

I can’t believe that it’s been 2 years since I first used Hibernate Annotations. This blog was like a flashback for me, as I experienced a similar error. You would think a simple abstraction on top of the Configuration class (maybe just a factory for it?) would be enough to deal with this, as reading the hibernate.cfg.xml (i.e. the presence of a mapping element with a class attribute) file should be sufficient to imply which subtype of Configuration to use.

Well, there are lots of applications where you don’t need that level of flexibility because you have more control over the app. Using annotations is:

1) simpler
2) better typed (fewer class names in external files)
3) loses none of the flexibility since you can override the annotations in xml if needed

That said, I don’t think either choice is right or wrong - different people will find or the other better in this scenario.
