Comprehensive - read this and pass your SCBCD 5 for EJB3
on 13 June 2008
This book is all you need to read if you want to know about EJB3, and it helpfully makes comparisons between EJB2 and EJB3 throughout the text.
If you read chapters 1 to 17 of this book, that's all you need to know to sit the Sun Certified Business Component Developer exam (JEE 5). I sat it this week and got 90%, using only this book and the Whizlabs mock exams as a reference.
The only down point of the book is that it must be read like a novel to really understand EJB3. It's not an easy lookup reference book, you can't just dip in and out of it. For example, different aspects of persistence contexts and transactions are featured in more than one chapter, which is why it is better that you read the book from start to finish. You won't need to read chapter 17 onwards unless you want to know about web services.
It might seem like a long haul but it is definitely worth spending the time reading this book.
