JPA for dummies
I just came across this very good article which explains Java Persistence API with EJB3. The article is written in very simple and lucid language. Even dummies like me have no problem reading up and understanding what JPA is. I just could figure out that there are two parts to this tutorial.. I am not sure whether it has more parts..
