Make the servlet use JSP

Here is a review of what the web application does:

1 The browser sends the request data to the container
2 The container finds the correct servlet based on the URL, and passes the request to the servlet
3 The servlet calls the Model class for help
4 The Model class returns an answer, which the servlet adds to the request object
5 The servlet dispatches to the JSP
6 The JSP gets and answer from the request object
7 The JSP generates a page for the container
8 The container returns the page to the user
