I actually own Manning's SCWCD Study Kit 2nd Edition. Many typos, a few serious mistakes, and a bit dry to read, but not as bad as some people pretend it to be. However, so many people recommend HFSJ here, that you should give it a try.
Also take a look at Core Servlets & JSP, and More Servlets & JSP, both by Marty Hall. The 2 books above, plus HFSJ, will take you a long way. Not only in passing the exam, but in your professional career. Most of the developers at the shops that I have worked at have Marty Hall's book (core servlets) on their shelves. It's also the book I have refered to the most, when I need to look something up.
