ParameterParser uses the parameters from HttpServletRequest.getParameterMap(), so it doesn't distinguish between parameters sent via post or via get. In other words, you can get posted form data the same way. :)
However, if this is going to become a complicated application, i'd recommend you use an action-based framework (like Struts, Stripes, Spring MVC, or others) to handle form posts in an "action" class. If it remains a pretty simple database back application, you might use something like Velosurf to handle updating the database. On 12/21/06, Markus Auchmann <[EMAIL PROTECTED]> wrote:
Thanks for the explanation it just works perfectly :) Another question. I want to create a guestbook with velocity and viewservlet. Therefore I want to create a form which posts the data.
