Another vote for this issue. This is the #1 issue (by a long shot) from the community in terms of votes and in terms of # of people watching. It would be great if RESTEasy could add the #1 requested feature of users.
I understand there is a big debate over if having WADL is too formal for REST services or if you are doing REST "right" by having it. Why make this decision for users? Provide the feature and both camps can use it or not use it as they see fit.
For me, the thing that tips the balance in favor of having this feature is the support of testing tools to read the WADL of a REST service and be able to stub out at least a starting point for test cases. Not needing to build test cases from complete scratch is a huge benefit.
