Hi,
I'm really struggling (going on 2 or 3 days now) to get Felix to work with a
Grizzly Http Service deploying Jersey. I've googled like crazy to
try and resolve on my own, but no luck. I'm hoping that I'm overlooking
something simple that someone can point out to me. Everything is
ACTIVE/RESOLVED from an osgi perspective. My problem appears to be that
Jersey cannot locate my resource file. Along with Jersey's inability to
find my resource class there's also a stack trace (ServiceConfigurationError)
that I'll post below. Also, I've posted this on the felix site as well, but
haven't received any help.
Thanks,
Dave
