我正在尝试从公共 Web 服务创建一个测试客户端： http ://www.webservicex.com/currencyconvertor.asmx?WSDL

使用 Eclipse 和 CXF 2.x 来自动生成 WS 客户端。到目前为止看起来不错，但在执行时我只收到以下错误。我发生了我调用 webservice 方法conversionRate，它也是自动生成的，如下所示：

@WebService(targetNamespace = "http://www.webserviceX.NET/", name = "CurrencyConvertorSoap")
@XmlSeeAlso({ObjectFactory.class})
public interface CurrencyConvertorSoap {

    @WebResult(name = "ConversionRateResult", targetNamespace = "http://www.webserviceX.NET/")
    @RequestWrapper(localName = "ConversionRate", targetNamespace = "http://www.webserviceX.NET/", className = "ConversionRate")
    @WebMethod(operationName = "ConversionRate", action = "http://www.webserviceX.NET/ConversionRate")
    @ResponseWrapper(localName = "ConversionRateResponse", targetNamespace = "http://www.webserviceX.NET/", className = "ConversionRateResponse")
    public double conversionRate(
        @WebParam(name = "FromCurrency", targetNamespace = "http://www.webserviceX.NET/")
        Currency fromCurrency,
        @WebParam(name = "ToCurrency", targetNamespace = "http://www.webserviceX.NET/")
        Currency toCurrency
    );
}

我怎样才能找出错误来自哪里？这里可能有什么问题？

错误：

解决方案是不要删除自动生成的package-info.java. 通常，在创建普通 Java 项目时，可以节省地删除此工件。但在 web 服务的情况下，它包含强制性定义。
