Query: A great text and reference book to learn sevlets and JSP

I found the text easy to read and follow. It helps you a lot to get started both with servlets and JSP and, what is very important where to get the software, how to install, configure and use. It is well structured and easy to find an answer. The sample code is self descriptive and can be used for real life solutions.
