The first version of the controller servlet
Our plan is to build the servlet in stages, testing the various communication links as we go. In the end, remember, the servlet will accept a parameter from the request, invoke a method on the model, save information in a place the JSP can find, and forward the request to the JSP. But for this first version, our goal is just to make sure that the HTML page can properly invoke the servlet, and that the servlet is receiving the HTML parameter correctly.
