AppFoundation and Hibernate

Flow
1

I should use hibernate as DB layer in my Vaadin project.

Also i need AppFoundation to be integrated with my Vaadin project.

I read that, with a IFacade abstraction, it is possible to use Hibernate with AppFoundation in the page:

http://code.google.com/p/vaadin-appfoundation/wiki/Persistence

Now three questions:

  1. I am not a newbie but i need a tutorial to use AppFoundation with Hibernate, searched, but could not find so far.

2)If there is no tutorial already, could you advise a path with some resource?

  1. Also i need courage to roll up my sleeves, i am afraid of giving up in the middle about this unattempted experience.
