[Jersey] Re: Unmarshalling JSON using MoxyJsonProvider

Thanks for the example, Aris! Hm, I don't see the Activity class in the
Jersey or MOXy APIs, so I'm inferring that this is the POJO class. Is that
correct? And setTags is just a way to initialize the data?

Also, I'm guessing that the endpoint at /activities has been coded to just
echo back the JSON object sent to it; am I reading that correctly?

Again, thanks for your time! It's pretty exciting getting my teeth back
into Java.
