This tutorial focuses on using Servlet's and JSP the right way. Servlet and JSP have evolved over the years, and these days there is often more than one way to do things. For example, this tutorial uses EL and JSTL not JSP scriptlets, it uses JSPs in a Model 2/MVC style not in a model 1 style, etc. Consider it a tutorial that focuses only on the best practices and not the legacy ways to do things. Huge and helpful tutorial!!!
