Spring + Hibernate + JPA
As of now I have a working Spring application with persistence. However now I want to use Hibernate with JPA to do all of my database activities. I want to do this using an entitymanager. 

I've been reading many documents and tutorials on this matter, I've been getting confused on whether I need a persistence.xml file or not. Also I've been getting confused on how to setup my applicationContext.xml file as well. 

Does anybody know of a good site to look at in order to learn Spring + Hibernate + JPA + using EntityManager?
