Hi Yy,
I first bought Mannings
SCWCD Exam Study Kit Second Edition. That's complete if you like a front-to-back approach, but there's a lot of typos and inconsitencies which make you wonder if all that you're learning is correct.
I recently bought
Head First Servlets and JSP because I heard a lot of good feedback. I must admit, it's a very very very good read, and very much worth your $$$. It is very well written, complete and often very funny! Further more it focusses on the nuts 'n bolts for the exam. If I should recommend somebody a book for studying the SCWCD this would be it!
[I don't know your book Charles, sorry...]
