java 访问带身份认证的web页面（或者webservice）

Question

各路大神 请指导一下： iis里面开启了windows身份认证，java程序访问该web应该如何加身份认证？ 谢谢！

代码如下，该如何改？

try {
URL realUrl = new URL(url);
URLConnection connection=realUrl.openConnection();
HttpURLConnection httpURLConnection=(HttpURLConnection)connection;
httpURLConnection.setDoOutput(true);
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setRequestProperty("content-type", contentType);
outputStream = httpURLConnection.getOutputStream();
outputStreamWriter = new OutputStreamWriter(outputStream,"utf-8");
outputStreamWriter.write(str);
outputStreamWriter.flush();

        if (httpURLConnection.getResponseCode()>=300) {
            throw new Exception(
                    "Http Request is not success,Response code is "+httpURLConnection.getResponseCode());

        }
        inputStream=httpURLConnection.getInputStream();
        inputStreamReader=new InputStreamReader(inputStream,"utf-8");
        bufferedReader=new BufferedReader(inputStreamReader);
        while((resultLine=bufferedReader.readLine())!=null){
            if(!resultLine.trim().equals("")){
                 stringBuffer.append(resultLine).append("\n");  //读完每行后换行
            }   
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

正在写web services ,一般是需要参数的，你把用户名和密码做成参数传递过去试试。
