Hi Laird,
I think there might is a bug in the MBW sorting algorithm.
https://jsr311.dev.java.net/nonav/releases/1.1/spec/
spec3.html#x3-440004.2.2
4. Sort the selected MessageBodyWriter providers with a primary key
of media type (see section 4.2.3) and a secondary key
of generic type where providers whose generic type is the
nearest superclass of the object class are sorted first.
and i am doing this the opposite for the secondary key, doh! So
MessageBodyWriter<String> is sorted before MessageBodyWriter<Object>,
rather than the other way around.
I am not sure if that issue is causing you problems or not. Hard for
me to tell without looking at all your code.
Anything in the logs to indicate an error constructing
RestDataSourceAdapter?
Paul.
