Chris,
I have been reading about the new EJB3 specification, and how the design incorporates POJO's and even resembles Hibernate in certain ways. Do you have any predictions on how well received EJB3 will be accepted? Does your book address this?

Thanks, and I look forward to checking out the book!
Eric

Entity beans from EJB3.0 and Hibernate and JDO are all converging toward the same structure, partially because some of the same people are involved in all 3 camps. I think EJB3.0's response is the most delayed, as in some of the design was in a way to keep up with JDO which has now been superceeded in a lot of ways by hibernate.

Eric,

I am sure that EJB3 will be widely used because:
(a) Its a huge improvement over EJB2
(b) its a standard and many people like to use standards
(c) Its backed by big companies

However, despite the hype surrounding EJB3, Spring and Hibernate offer a richer set of features. Moreover, because Spring and Hibernate are open-source frameworks and are decoupled from the application server they will likely evolve at a much faster rate.

Chapter 10 of my book describes how to implement POJOs with EJB3 and also compares it to those other frameworks.

The sample Chapter 1 also shows a few limitations concerning the current draft.
