Having passed the first exam, I started studying for my SCWCD exam. But then after working with Jakarta Struts for a while, I don't know whether it's worth while to take the SCWCD exam. I surely hate the JSP snippets, it makes JSP pages unmaintainable. So, I seriously do not know how SCWCD will help me to do my job better. Dilemma! Dilemma! We're not in college anymore; hence anything we learn should be worth the money, time, and effort.
That's my humble opinion.
Hence, i turn my attention to this book; I skimmed through it for the first couple of days and realize that this is the certification that I shoud pursue next; SCBCD instead of SCWCD. I look beyond the certification; the ability to program EJB to do a better job. Having intrinsic reasons to do something, for example learning the subject for the sake of the knowledge and implementation, is far better than having a piece of paper that says you are certified.
I started reading the book and i honestly just cannot put it down. So far, the items covered in this book make a lot of sense to me; in terms of how i can use them to write better codes and design better EJB. I am a visual learner. Thus, the graphics in this book really enhance and expedite my learning process. When I read them, I understand the concepts instantly! Plus, they're funny. It makes the learning process very fun! Make sure you have some notebook and draw/sketch the important concepts. They help understand some complex points presented.Read more ›
The most complex part of the subject is entity beans whose methods are inconsistent with stateless session beans of the same name. I think after reading the book one needs to rethink even using entity beans for anything because of the overhead and complexity. I would really be concerned about performance so testing a vertical slice would be a necessity.
The real question at this time is whether you should learn and get involved with EJB 2 at all - since EJB 3 is destined to completely simplify the whole process - eliminate the home interface, ejb component objects, etc.
Using POJOs (Plain Old Java Objects) to accomplish the same task is the strategy of the new light, non-J2EE standards based frameworks such as Spring. It's anticipated that EJB 3 will be very Spring like - whether they hide all the EJB 2 details under the covers or re-architect the whole framework (and hopefully get Spring like performance). There is also the whole notion (and nightmare) of testing your bean using separate containers that one should consider before embarking on the EJB 2 path. All in all, I enjoyed the book's style, and if nothing else, it will help you appreciate the simplicity (hopefully) of EJB 3 when it becomes available.
If you need to support legacy EJB architectures, this is the book to use to learn EJB 2. If you are architecting a new solution, wait for EJB 3, or better yet, look into the light weight non-standards based frameworks like Spring.
and like to concentrate only on the "essential raw matter" this
might not be the book for you. A fine example of the fact that only really serious people are not afraid of being funny...
I teach all levels of Java including EJBs and advanced J2EE in a variety of advanced undergraduate software development courses to students at Purdue University. It is particularly challenging to motivate students to study and learn the intricacies of J2EE Architecture and Software Design, and its eventual deployment onto real-world Application Servers.
Head First EJB stands alone in its treatment and presentation of advanced EJB concepts. This book rocks!
I have always said that a bad teacher can take the most inherently interesting material and make it boring, but a great teacher can take the most inherently boring material and make it exciting.
I have added this book as one of the required texts for future offerings of my advanced undergraduate "Enterprise Application Development" course.
I congratulate the authors on this marvelous, highly-readable and enjoyable body of work.

I got excited upon seeing the April 2013 publication date. Unfortunately, this book is a repackaging of the 2003 book, and hence covers EJB 2.0 (very well, I'm sure). Read morePublished on January 6, 2014 by Elissa Feit
