I have the WADL extension working on my project but I'm trying to get the auto-transformation to HTML working as described in the Restlet in Action book. The book says to include the Xalan 2.7.1 library which I have done. I'm using 2.1 SNAPSHOT for all Restlet libraries including the WADL extension library. Here are a couple of log entries and the stack trace:
