Here is what you can do. Inherit your 'action servlet' from the HttpJspPage in
question ( or vise versa), and then inherit your JSP page from that. Post your
forms to 'self' (the default). You will have to add some logic to your service()
method, or your doPost() etc. whichever you are using so that it knows when to
simply load the page, by calling the 'jspService()' method, and when to process the
form.
