I want to handle these myself because wink does not format them into xml/json, and if it did, would still be choosing its own format rather than mine. I have an exceptionMapper which handles WebApplicationException but from the exception I get there, I cannot figure out how to get a description of the cause. I can get the stack, which normally isn't helpful, and I can get the http status code from the response, but trying to get a string saying "there is no handler for method PUT on resource /wibble/" seems to be impossible. Has anyone attempted this? Did you find a solution? The closest I can get is parsing the http status code and writing a description stream for each, but then I have to parse the Request object to work out what the user called.
