找不到类型的响应对象的MessageBodyWriter：com.sun.jersey.api.json.JSONWithPadding媒体类型：application / x-javascript

我正在尝试在我的骨干应用程序上使用jsonp . 在我的webservice中，我正在尝试使用Jersey库来使用JSONWithPadding响应 .

问题是，看起来不支持“application / x-javascript” .

我的代码是：

@GET
@Path("/issues/jsonp")
@Produces("application/x-javascript")
public JSONWithPadding getIssuesJsonp(@Context HttpServletRequest req,
    @PathParam("ppid") String qppid,
    @QueryParam("callback") String callback) {

Principal principal = req.getUserPrincipal();
    String username = principal.getName();

try {
    List<IssueDTO> list = service.getIssuesDTO(username, qppid);
    IssuesResult r = new IssuesResult();
    r.setIssues(list);
    System.out.println("CALLBACK:" + callback);
    return new JSONWithPadding(r,callback);
} catch (Exception e) {
    String message = "Internal Server Error";
    LOG.error(message, e);
    Result r = new Result(PPStatusCode.INTERNAL_SERVER_ERROR, message);
    return new JSONWithPadding(noCache(500, r),callback);
}
}

结果是：

Etat HTTP 500 - Could not find MessageBodyWriter for response object of type: com.sun.jersey.api.json.JSONWithPadding of media type: application/javascript

有人能帮我吗 ？
