Hello,
I got the Bookmark example, it has jersey e JPA integrate, I would like to
add EJB lib, and I did. My question is, do I need to set up the web.xml
file? What should I add? Currently my web.xml is like bellow. Do I need to
configure something else? I am getting NullPointerException when I made my
BaseDAOImpl with @Stateless anotation implementing a @Remote interface
BaseDAO and on the BaseDAOImpl I am injecting with @PersistenceUnit on
EntityManagerFactory, but I am getting NullPointerException, can someone
help me please? P.S.-> My Resource class is calling the BaseDAOImpl.
