Re: Trying to get a portlet to work [was Re: Administration Portlet doesn't work]

I don't get this either. And its not even like it isn't possible: Websphere
Portal, Jetspeed 2 and JBoss Portal all do not(!) require me to write a
specific web.xml. I can export my webapp as a war file, deploy it to the
server and use its admin tools (built as part of the portal GUI) to deploy
the available portlets to one or more pages.

How hard can it be do simply parse the portlet.xml (that is done anyway) and
create the necessary servlets (if at all) on the fly? I don't see why the
container should even waste its resource by rewriting the deployed
web.xmlfirst, just to parse it again.
