JAX-WS wrapper compilation

[Benson Margulies]

@WebMethod
    @ResponseWrapper(className = "com.basistech.rnt.ws.TranslateResponse")
    List<TranslationResult> translate(@WebParam(name = "job")
TranslationJob job,
                                      @WebParam(name = "options")
Options options) throws RNTException;

A response wrapper, but no request wrapper. I see the ASM code in JAXB
at work on the response. Howcome?
