I often receive a request from my readers and fellow Java developers about book recommendations to learn Servlet and JSP, two of the key web technology for server-side web development in Java. Unfortunately, there are not many good books to learn Servlet and JSP for Java web developers. Despite being the most popular Java Web technology, there are very few good books to learn Servlet and JSP. The one book which everybody will suggest to you is the Head First Servlet and JSP, which is indeed one of the best books but it's outdated now. It doesn't cover the latest development in Servlet API, particularly Servlet 3.0, and also not been updated for the last 7 to 8 years, but considering others, it is still an excellent book to learn Servlet and JSP.
