[undertow-dev] REST routing

I was curious what the best practices would be for url routing with many endpoints. For example POST /user/ GET /user/{userId} GET /document/{documentId} ContentType=appliction/json (only respond when json is requested) What would be the best option for this? I was able to achieve most of what i wanted using the PredicatesHandler class. Is this a good choice? This would build a List of PredicatedHandlers as well as the fall through handler which I would use as a 404. I got an example working using the text predicate format method[GET] and path-template[value=\"/user/{userId}\"] Is this a good approach or are there better recommendations? Thanks, Bill
