Hi,
I've been using the Jersey implementation recently, but was a bit baffled about the fact that you cannot express required query parameters. I read lots of entries on various forums - the matter has been discussed, but not implemented. I think Jersey should have this functionality by default. I have a solution at
http://developcorner.blogspot.dk/2013/01/custom-wadl-generator-in-jersey.html, but maybe there is a reason why the functionality never made it into Jersey?
Best regards,
Morten Lynge
