Adding to what Andrew has said. You could make this simpler by just
creating a jsp file(index.jsp) and putting it inside your application
folder (in this case jsp folder and not WEB-INF).
Simply delete web.xml if it contains nothing or if its giving any error
during start up of the server.
In index.jsp you could put "hello world"

In your browser try to open it (http://127.0.0.1:8080/jsp/index.jsp I
am presuming that you would have not changed the port number)
I would also like to presume that you don't know how servlets can be
invoked. So you should refer some book, how to deploy a servlet.

Hope this helps
