Thanks David...
Looks like the problem has to do with that fact that an Object instance is
being returned....
The method.getReturnType() is used when searching for providers...

Subject: RE: How to use CXF and JSON
When I do the below I get the below exception. EnvFromHourlyWrapper
is
my
wrapper object that holds a List of the objects that I want to return.
I believe if you Google for "JAXRSOutInterceptor
writeResponseErrorMessage WARNING: No message body writer has been found
for response class", you'll find an explanation of this.
