This was what it took:
PortletDD pdd = PortletContextManager.getManager
().getPortletDescriptor(appName, portletName);
I had to stash the appName and portletName in Sakai data structures
so I could regurgitate them at the right time.
It is too bad that I had to go to such effort - in a sense the
doRender call does not need as much information:
portletContainer.doRender(window, req, bufferedResponse);
doRender finds find all the necessary data about this Portlet- it
would be nice someday to have the container to be able to hand me
back a PortletDD with no more information than that which is present
in the doRender.
now perhaps I am complaining about what is *my* responsibility and
what is the container's responsibility - but if the container has the
right code to resolve form effectively the windowId - then I
theoretically should be able to ask for PortletDD knowing just the
window id and request(perhaps).
Just thinking out loud.

I would like to only do so if the Portlet supports the HELP or
Edit modes.
I am in the render code about to call
portletContainer.doRender(window, req, bufferedResponse);
and have access to all of the following structures:
PortletContainer portletContainer = getPortletContainer(context);
RequiredContainerServices rs =
portletContainer.getRequiredContainerServices();
PortalCallbackService pcs = rs.getPortalCallbackService();
PortletURLProvider pup = pcs.getPortletURLProvider(request, window);
pup.setPortletMode(new PortletMode("edit"));
String editUrl = pup.toString();
pup = pcs.getPortletURLProvider(request, window);
pup.setPortletMode(new PortletMode("help"));
String helpUrl = pup.toString();
So I can derive what the right URLs are - but cannot figure out
whether I should emit these URLs.
I could figure this out if I could get my hands in the
InternalPortletWindow or the PortletDD. But it seems that I
cannot access these things until the Container has built the
PortletRequest structures - at which point it is trivial because I
can call isPortletModeAllowed() if I had those structures.
It would seem to me that I should be able to lookup a PortletDD
somehow...
