Question

我有泽西客户端和球衣服务器。对于自定义异常，我创建了一个实现的提供程序类 avax.ws.rs.ext.ExceptionMapper，我回复了

ErrorResponse errorResponse = new ErrorResponse();
return Response.status(Response.Status.INTERNAL_SERVER_ERROR).entity(errorResponse).type(
            MediaType.APPLICATION_XML).build();

现在在客户端我正在做如下

if (response.getStatus() == Status.OK.getStatusCode()) {

    CustomeResponse cresponse = response
                    .getEntity(CustomeResponse.class);
}else{
ErrorResponse errorResponse = response
                    .getEntity(ErrorResponse.class);
throw new CustomException(errorResponse.getErrorMessage(),
                    errorResponse.getErrorCode());

}

但是每当我的服务器有空指针异常时，我在客户端

中得到以下异常

Aug 19, 2014 12:03:37 PM com.sun.jersey.api.client.ClientResponse getEntity
SEVERE: A message body reader for Java class com.custom.exception.ErrorResponse, and Java type class com.custom.exception.ErrorResponse, and MIME media type text/html; charset=utf-8 was not found

SEVERE: The RuntimeException could not be mapped to a response, re-throwing to the HTTP container
java.lang.NullPointerException

我可以映射空指针和其他运行时异常，以便在客户端抛出有用的错误代码。请帮忙并提出建议。

如何在Jersey服务器中映射Null Pointer Exception
