java - 自动生成的Web服务调用失败，并出现编码错误？

我正在尝试通过公共Web服务创建测试客户端：
http://www.webservicex.com/currencyconvertor.asmx?WSDL

将Eclipse与CXF 2.x配合使用可自动生成WS Client。到目前为止看起来还不错，但是在执行时我只会收到以下错误。
发生这种情况时，我将调用webservice方法conversionRate，该方法也会自动生成，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
    );
}

我如何找出错误的来源？这里可能出什么问题了？

错误：

最佳答案

解决方案是不要删除自动生成的package-info.java。
通常，在创建普通的Java项目时，可以节省该工件。但是对于Web服务，它包含强制性定义。
