This is more of a general portlet question.

I have a portlet that wants to display a dynamic image (*) as part of
its output.

In a traditional HTML application, I would build a URL to a servlet
and the servlet would build the image and send a bytestream to the
client.

I want to do something similar with a portlet.

Is it possible to build such a URL?  I want to build a render URL and
have the handler for that URL build and return the image bytestream.


(*) This is really about Tapestry Portlet support.  The dynamic image
data is really going to be images packaged in JARs that need to be
exposed to the client.  Tapestry includes an engine service that will
access such things.  I'm trying to see if I can avoid using a Tapestry
servlet in anotherwise Tapestry portlet application.
