Vaadin + JPA+ Hibernate

Flow
1

Hi, I’m newbie of vaadin and jpa. I need create a project with vaadin, jpa2, hibernate and mysql.
what add-on should I use?
I saw JPAContainer and the sample code of addressbook, but this example is for eclipseLink and it haven’t a connection with db.
Is there an example for hibernate?
how do I configure the persistence.xml?
are there also examples of vaadin + jpa and hibernate with other add-ons?

thank you very much in advance

Actually, vaadin is a good framework but i cannot find enough examples or tutorials. They need to increase the variety of samples.
