Mmmm. Trying to set this up. The hello world JPEG and PNG examples were failing with an error quite like this:

To fix, in Resin, put <system-property java.awt.headless="true" /> in resin.conf under the <resin> tag. I am amazed this needed to be done — and more amazed that I couldn’t easily find an explanation for it with Google. Finally found it after looking at this message on resin-interest.

Update: Oops: http://cocoon.apache.org/2.1/installing/index.html#Headless+UNIX+and+PJA. Guess I should read more carefully.
