我调用用天气预报的Web Service总是调不通，各位帮忙看看呐！

代码如下：
接口：
public interface IWeatherWS {
public String[] getWeather(String theCityCode, String theUserID);
}

public class XfireWeatherWS
{

    public static void main(String[] args)
    {
        new XfireWeatherWS().getWeatherByCityName("北京");
    }
   
    private void getWeatherByCityName(String theCityName)
    {
        try
        {
            IWeatherWS weatherWS = null;
            Service serviceModel = new ObjectServiceFactory().create(com.linkage.xfire.weather.IWeatherWS.class);
            serviceModel.setProperty(CommonsHttpMessageSender.HTTP_PROXY_HOST, "代理名称");
            serviceModel.setProperty(CommonsHttpMessageSender.HTTP_PROXY_PORT, "8080");
           
            XFire xfire = XFireFactory.newInstance().getXFire();
            XFireProxyFactory factory = new XFireProxyFactory(xfire);
           
            String serviceURL = "http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx";
            weatherWS = (IWeatherWS) factory.create(serviceModel, serviceURL);
           
            String[] result  = weatherWS.getWeather(theCityName,"");
            System.out.println(result.length);
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }
}
？？？？？？？？？

这种问题拿来问. 一看就知道超时了.
没准你过几个小时再调用的时候又好了

国内的这些 Web Services 服务就是这样的

连接超时，可以先在地址栏上访问下url看能不能访问！服务端程序是否写正确了！

你现在浏览器中访问一下ws地址是否正确。
我认为很有可能是
String serviceURL = "http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx"; 不正确
