looking for a good starting point to using JBoss/JPA/Hibernate and EJB3.0 if anyone can point me at some good documentation or tutorials, it would be much appreciated. i already know how to use hibernate, and a little bit about JPA, but what i am really interested in learning is how to use JPA inside of a EJB and use the PersistenceContext and have the entitymanagerfactory be injected. i have tried several times with jboss and glassfish and could not get past a nullpointerexception when trying to persist an object. if anyone has experience gettings these technologies to work together peacefully i would love to know how. thanks.
