Spring MVC and Grails[1] offer a nice way to convert incoming request data into
domain objects. Conversion errors, like "xy" -> Integer, are reported.


I want to do something similar with JAX-RS, but don't know how I could do it
elegantly. A MessageBodyReader came to my mind, but how to report conversion
errors to the method in the resource class, which receives the conversion
result?
