The following documentation is a guide on how to use EJB 3. You can also obtain more information regarding some of the topics that will be discussed

The site has been comprised of reading the following books and real world experience, if you are new to EJB I highly recommend that you should purchase these books as it contains far more information than this web site contains and of course the Official EJB web site contains all the documentation you will ever need.

Please feel free to email me any constructive criticism you have with the site as any additional knowledge or mistakes that I have made would be most welcomed.

EJB 3 Books
EJB 3 in Action - Debu Panda, Reza Rahman and Derek Lane This book is a lot easier read than the O'Reilly version, it is definiately more of a beginners book. It covers just the basics which what a beginner needs and also cross-references the old EJB 2 version, which makes a case for upgrading to EJB 3. There is also some referencing with Spring which all helps when learn a new technology.
Enterprise Java Beans 3.0 - Richard Monson-Haefel, Bill Burke This book is a very heavy read and if you are new to EJB (like myself) then I advise you to read the above book first, although a very good book try to pace yourself otherwise you will become easily bored.
Java Persistence with Hibernate - Christian Bauer, Gavin King This book goes in to much more depth than the two books above regarding Java Persistence, so it compliments them both. As with all the Manning books they are easy to read and ideal for a beginner developer like myself.
Beginning POJO's - Brian Sam-Bodden Just started to read this so will update his page when finished
POJO's in action - Chris Richardson Just started to read this so will update his page when finished
Head First EJB - Kathy Sierra, Bert Bates I love the Head First books, they are fun and very easy reading, although this version is dated (EJB 2), it worth reading as you get a background on what EJB 3 is trying to archive, also some of the topics are still irrevilant and help to explain in a graphical way.
