java访问WebService返回xml数据生成为本地文件

Question

部分代码如下：
public class DomXMLString {

private static String SERVICES_HOST = "www.webxml.com.cn";

private static String NETDATA_URL = "http://183.131.242.70:8089/ship/interface/shipInfoService.asmx/getTask";

private static String LOCAL_PC_SAVEFILE_URL = "E:Myeclipse/sy_Task.xml";

private DomXMLString(){}

public static void main(String[] args)throws Exception {
    Document document = getTask(NETDATA_URL);
    helloOK(document,LOCAL_PC_SAVEFILE_URL);

}


private static Document getTask(String netXMLDataURL) {
    Document document = null;
    DocumentBuilderFactory documentBF = DocumentBuilderFactory.newInstance();
    documentBF.setNamespaceAware(true);
    try{
        DocumentBuilder documentB = documentBF.newDocumentBuilder();
        InputStream inputStream = getSoapInputStream(netXMLDataURL);
        document = documentB.parse(inputStream);
        inputStream.close();
    }catch(DOMException e){
        e.printStackTrace();
        return null;
    }catch(ParserConfigurationException e){
        e.printStackTrace();
        return null;
    }catch(SAXException e){
        e.printStackTrace();
        return null;
    }catch(IOException e){
        e.printStackTrace();
        return null;
    }
    return document;
}
运行提示错误为：

之前也查了一些资料，想请问是不是我设置的路径有问题以及解决办法，求大神指点迷津

/**

* @param serviceUrl 服务名
* @param nameSpace
* @param methodName 执行的方法名
* @param paremateArrs 参数数据数组
* @param qNameArrs 变量数组
* @return
*/

public static Object CallSoapService(String serviceUrl ,String nameSpace,String methodName, Object[] paremateArrs,Object[] qNameArrs){

String endPoint = serviceUrl;

String actionUrl=nameSpace+methodName;

Object returnObj = null;

try{

Service service = new Service();

Call call = null;

call = (Call)service.createCall();

        QName qName = new QName(nameSpace,methodName);   
        call.setOperationName(qName);  
        call.setSOAPActionURI(actionUrl);  

        for(int i=0,len=qNameArrs.length;i<len;i++){  
             call.addParameter(new QName(nameSpace,qNameArrs[i].toString()), org.apache.axis.encoding.XMLType.XSD_STRING,  
                    javax.xml.rpc.ParameterMode.IN);

// 调用获得智慧社区的新增的用户信息
public static void main(String[] args) {

String url="http://221.226.86.35/webservice/UserOUService.asmx";

String method="GetFrameUserRecord";

String parameter="2016-09-05";

String namespace="http://tempuri.org/";

CallSoapService(url,namespace,method,new Object[]{parameter},new Object[]{"date"});

}

public static void main(String[] args) {  
    String url="http://172.22.173.21:8086/xinfang/services/xfinfoPhone";  
    //方法名
    String method="queryByIdMydPj";  
    //参数
    String parameter="{'xfid':'NJ2016010103390'}";  
    //命名空间
    String namespace = "xfinfoPhoneService";
    //最后一个参数随便填
    CallSoapService(url,namespace,method,new Object[]{parameter},new Object[]{"asd"});  
}  

}

这有短源码你参考一下，好像需要引入xfire jar包。很久了 记得不是很清楚了
