I was in a Law sciences college when I started reading this book, I guess it's the major thing I remember about it :D It's not really valuable unless you really want to know exactly how things work with Ajax. Nowadays, if you're using JEE, frameworks provide Ajax implicitly. So you'll probably won't need this book unless you want to do a framework by yourself.
