Hey!
You are on correct track with the doGet responding with the HTML
with an HTML form, which POSTs parameters back to the Controller Servlet.
Now just just get those parameters in the Controler Servlet and decide on
your next process (i.e., Java Bean). Or, get a Servlet Context,
a Request Dispatcher and just forward to your next JSP or HTML.
I suggest you get a book on Servlets, go to Sun website and see this
list's archive for many many examples of Model View Control methodology
for servlets.
Sans adieu,
