Sun Certified Web Component Developer Study Guide (Exams 310-081 & 310-082) (Oracle Press) ReviewI got this book partially because I prefer more of a textbook format than the Head First books. This book's format was more straightforward, so I got it along with the Head First Servlets and JSP. However, I have found a lot of errors, inconsistencies and confusing explanations in this book. Some of the errors are minor, but others really cause fundamental confusion. I'm searching for an errata for the book now. (There may not be one -- I'm not finding it yet.)

Although the Head First books have a comic, cartoonish quality that I don't generally care for, I must say that their editing is better, their explanations are always understandable, and I find myself going to that book to clear up my confusion with this one.
That being said, there is a lot of very good information in this book and some of the explanations and examples are pretty good. You might consider getting both books because they both cover the material in different ways.
I was tempted to give the book four stars, but I've just hit another few errors that are really irritating. (The author is trying to explain the difference between the forward() and include() functions for handling servlet requests. But his code examples mistakenly are showing forward() where apparently he meant to type include(). These examples do not match the explanation at all. See pages 183 and 184.)
Another egregious error: In the Head First Servlets & JSP book, they make a point of saying "You need to recognize WRONG method names like: getPrintWriter(), getResponseStream(), [...]" etc. And there's a big X in a circle on top of these names. Look at the SCWCD book by D. Bridgewater on page 179. Guess what method he uses inside the code example -- getPrintWriter() !!! (Gee, and I was wondering why my code would not compile.) In that SAME code sample, you can see him getting a PrintWriter object and calling the "write" method on it. I was perplexed by this because I saw them using the "println" method in the same situation in the Head First book. Well, apparently there is a difference, even though the code does work. Sierra and Bates in Head First make a point of saying you should use "println" with a PrintWriter and a "write" with a ServletOutputStream. They explain why, of course. I don't know about you, but these sorts of errors are confusing. I'm not even mentioning the multitudes of small typos throughout the book, like: java.servlet.forward.path_info. (servlet is in the javax package, not java.)
In any case, the book might be worth getting, and if you are able to find an errata it would make the book much more usable. If you do not find an errata that covers all of these errors (I've only mentioned a few), then be sure to get some other resource to check this one against so you can understand parts that are erroneous or confusing.Sun Certified Web Component Developer Study Guide (Exams 310-081 & 310-082) (Oracle Press) OverviewAn integrated study system based on proven instructional methodology, this book and CD package shows you not only what--but how--to study for the SCWCD exam.
