How do you handle extension custom negotiation like foo.xml or foo.json
automatically in jersey?
I can't find any documentation on it. The only thing I have found is this
thread, https://jersey.dev.java.net/servlets/ReadMsg?list=users&msgNo=2718,
that references this issue,
https://jersey.dev.java.net/issues/show_bug.cgi?id=108.

My guess is the client calls foo.json.
The REST method has two @Produces mime types for xml and json.

@Produces({"application/xml", "application/json"}


But how does the method know which one was requested by the client?
