Java library for content negotiation

Hi all,

I want a pluggable library that performs generic content-negotiation.
I found the Pubby source code [1] but I am wondering also what
alternatives there are that have possibly been released as small
libraries. I don't want to either rewrite the wheel or import more
than I am going to use.

How do other projects do content negotiation in Java? (Could the
content negotiation part of pubby be released as a separate library?)

Cheers,

Peter
