  <!-- In Tomcat 7 and other servlet 3.0 containers, you can use @WebServlet("/urlPattern")
       in the Java source code instead of using the servlet and servlet-mapping tags here.
       In fact, the ENTIRE web.xml file can be totally omitted with servlets 3.0. However,
       when you make a new Dynamic Web Project in Eclipse using the Tomcat 7 configuration, 
       Eclipse totally omits the web.xml file, and has no option to insert it for you. 
       So, already having a small web.xml with the legal syntax is helpful  in case you 
       want to use some of the standard web.xml entries instead of annotations.
