Spring 3 EJB 3.1 JPA 2

I am looking for a template project a tutorial of how to build Spring 3 + EJB 3.1 + JPA 2 application. Any references or advices warmly appricated.

UPDATE#1 http://twasink.net/blog/2007/01/using-spring开发者_如何学运维-with-ejb-3/ still looking for more answers

I'm not aware of tutorials or sample projects, but:

The general way of integrating Spring with EJB is described in the chapter 20. Enterprise JavaBeans (EJB) integration, the JPA setup will probably use JNDI and is described here.
