Dan,

When I completely cleaned out the container, rebuild my stuff out to a
KAR, and restarted, my service works, except when I try to click
through into the WADL, and I get the following.

I will try to recreate the problem with the annotations, if you would
tell me what to type at the karaf prompt to investigate the package as
you requested.
