If your looking on a book that will give you a solid foundation on the servlet/jsp technology THAT is the book for you.
I used that book to pass my exam.
The only reason why you might not like it, is if you like the head first style. Its very unique. I love it, but I could see why some people wouldn't.
I enjoy the style because it almost mimiks an interactive lecture. Its like attending a course, not reading a book. Its awesome.
As for the content? Well if your looking for beginner to advanced topics this book will cover it all but if you just want advanced-->expert then this book may not be what your looking for.
Thanks for the responses. I'm not even looking to pass the exam (or take the test). I just need to LEARN jsps and servlets. Is there a way I can see what the chapters are? I ordered the book online but I can't find a chapter listing anywhere.
The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
Don't be afraid of buying this book, "because I don't want to take the exam". This book covers everything you need to know about jsp/servlets/tomcat It just so happens that you could pass the exam using the book.
I had no clue of the issues in Sun's SCWCD exam. So I trusted Kathy, Bert and Bryan (authors of HFSJ) and did my exam preparation with just that one book.
