Thank you Andrzej! That is very helpful compared to the hack I was using (I
was registering JacksonJaxbJsonProvider.class). Your method is way cleaner
and I am glad Jersey exposes the features that way rather than having to
know specific classes.
I modified your method slightly to say client.register(new
JacksonFeature()) after creating the client, just to avoid creating a
config object. Hopefully that is not much less elegant and if it is I will
be happy to switch to the better method.
Thanks again!
