I am reading EJB in Action as a beginning book for my prep for SCBCD.
I am currently at Chapter 8 (ORM).
I am not able to understand ORM concept (Relationships, Mapping entities etc) from this book.
Please guide me to some other book in which these concepts (JPA,Entites,ORM) are explained in much better and simple way.
After reading 7 chapters from this book, i found this book lack enough practical examples to understand the working of MDBs,Session beans etc.So please guide me to some other book which good solid examples of EJB 3.0.
