AW: RequestDispatcher resource not available 2004-05-19 - By Nitschke Michael
Back
There lies the problem i don't know which servlets i would get, and i don't
want to reconfigure the web.xml and restart the server every time something
changes or get added.
Could you describe your second point a little closer, please?
We are using a database to store the mapping of urls to servlets.
I think web.xml would be pretty confusing if I register all my 200 Servlets in
it.

Hi,
- Define and map all your servlets in web.xml.
- Use the servlet-mapping url-pattern as your argument to the
getRequestDisptcher call.
