Sorry for the long title. So, here is the run down. I'm essentially building a java Document tree by adding nodes and the like. I have a particular RelaxNG schema that I want Document to build against.
Now, I can load and create the corresponding SchemaFactory and Schema instances on my local machine. I then add them to my Document. This all works when running on my local machine (Mac Snow Leopard, Eclipse Java EE Helios, latest Google Web Toolkit plugin). However, when I deploy to App Engine, I get the following error: # 2011-02-10 18:21:22.253 /labauthoringtool/genXML 500 1778ms 1913cpu_ms 0kb Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US;
