David,
I just added your Graffito portlets (Tree & Document) into a new psml file and made some minor changes (add config file and jsp).
Now you can see thoses portlets running in the J2 demo application.
Let me know if something is wrong.
It should be nice to have a common portlet app subproject. I have almost the same FileServlet in the Browser application :-)
Regards, Christophe
