Query: A great book to learn the ins and outs of servlets

This book not only gives you a great introduction to programming servlets (including hosting and configuration, chaining, etc.) but also delves into related topics such as HTTP tunneling and using introspection to simplify servlet programming. I especially liked the amount of JDBC/RMI information included in the book since many servlets written will want to interface to other Java servers or databases. Having written an article on servlets for BYTE, I was pleased to find this much information packed in the book. My only disappointment is that the author didn't include more on managing state with servlets (e.g. through cookies) and about the future of servlets (covering developments such as Servlet Beans, and the impact, if any, of EJB on the servlet standard). All in all, a great servlet book!
