Rahul Bhattacharjee, Test.do is the name that I put on my web.xml archive to be the reference that the client uses to call the servlet. Like this:
<url-pattern>/Test.do</url-pattern>.
Ben Souther, I suppose my classes are ok because I copy them from the book Head first, Servlets and
JSP. I check more than 1 time to see if I made a mistake there. The url that I am using is "http://localhost:8080/Beer-v1/Test.do", and it is the url that the book tell us to use.
Thanks for the reply people. I hope we can find out what I doing wrong.
