There's a reasonably stable and well-tested implementation that is  
used both in the Pubby and D2R Server codebases. See here:

This just does the negotiation part (that is, matching an HTTP Accept  
header against a list of media types that the server supports,  
including support for q values). It only supports media type  
negotiation, there's nothing for language negotiation or encoding  
negotiation in there.

The package works like this: You configure a ContentTypeNegotiator  
with the media types supported by your app. Then you use its  
getBestMatch(...) method to determine the best response for a given  
request. The PubbyNegotiator class has a pre-configured negotiator for  
a server that supports HTML and various RDF syntaxes.
