Question

我正在尝试使用soap weservice示例。该代码使用GeoIp webservice从IP地址确定国家/地区。当我执行代码时，我得到以下异常。

异常：

Exception in thread "main" com.sun.xml.internal.ws.fault.ServerSOAPFaultException: Client received SOAP Fault from server: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.NullReferenceException: Object reference not set to an instance of an object.

我的代码：

import net.webservicex.GeoIP;
import net.webservicex.GeoIPService;
import net.webservicex.GeoIPServiceSoap;

public class IPlocationFinder {

    public static void main(String[] args) {

        if (args.length != 1){
            System.out.println("you need to pass atleast 1 IP address");
        }
        else
        {
            String ipAddress = args[0];
            GeoIPService ipService = new GeoIPService();
            GeoIPServiceSoap geoIpserviceSoap = ipService.getGeoIPServiceSoap();
            GeoIP geoIp = geoIpserviceSoap.getGeoIP(ipAddress);
            System.out.println((String)geoIp.getCountryName());
        }
    }

}

如果先在sopui中获得响应，请使用soapui create xml并发送请求。然后检查您发送的xml是否包含所有字段并在soapui请求中匹配一个。

运行代码时，对象引用未设置为对象execption的实例
