I fixed my portlet.xml file but I don't think JBoss Portlal can handle a portlet that produces image/png data.
On the OpenSymphony message board, I found a discussion about producing image output from a portlet: http://forums.opensymphony.com/message.jspa?messageID=52699 anonymous wrote : | | Nils-Helge Garli wrote: | > Hm...
