A Basic Servlet

In this section, we are going to look at building and running a very basic servlet. Its purpose will be to service a request and respond with the request method used by the client. We will take a quick look at the servlet's source code, the steps involved in compiling and installing the servlet, and the HTML necessary to invoke the servlet.
