Hi Sergey,
I'm finally getting back to this... From a logging interceptor, I don't have
access to, e.g., UriInfo. All I have is a Message object... With respect to:
>> In addition, a CXF specific UriTemplate, available from the current

is there a way to query CXF to see which resource is a match, and then further
drill down to use this template-based approach?
Thanks!
