When I downloaded this book for free from theserverside, I thought I could not go too wrong, after all it is free. After spending more than a week with this book I realized that I have wasted one week time "for free". Here are the problems with this book:

1) EXTREMELY verbose -- Paragraphs are repeated again and again and again with the same information, worded differently. It should be possible to cut down the number of pages in this book by more than 500% (make the book one fifth of what it is) without losing any information.

2) Very Superficial-- As against what you would expect from such a fat book on EJB, this book actually hardly covers any topic in EJB in details. There are too many open questions and so many important topics are not even covered.

3) Poor treatment of new Java EE 5 features -- For example how does @Resource injection really work? Not a single fully working example.

4) Maybe inaccurate -- I'm not too sure about this but the authors talk about the @javax.ejb.Interceptor annotation. This does not even seem to exist according to the EJB 3 API documentation.



I would have given it one star rating, but since the book is free, I give it two stars.
