Hi Jonathan,
See here for another Freemarker template processor that works with Web
apps:
http://www.cwinters.com/blog/2009/04/03/jersey_freemarker_provider.html
Perhaps Chris knows a thing or two about Freemarker to help you out.
Are you using Servlet or another type of HTTP container?
This seems like some sort of Freemarker config issue to the location
of where your templates are. Perhaps you could test your assumptions
outside of Jersey by writing a little test app that attempts to get
the template directly ?
If you can wrap up a simple Jersey test app from within a maven
project i might be able to help you out with some experimentation.
Paul.
