 『求救』读取网页内容 为何报错
<%
String bufferStr=""; //用BufferedReader
java.io.InputStream getStream;
java.net.URL myURL=new java.net.URL("http://www.sina.com.cn");
java.net.HttpURLConnection
myCon=(java.net.HttpURLConnection)myURL.openConnection();
myCon.connect();
getStream=myCon.getInputStream();
java.io.BufferedReader myReader=new java.io.BufferedReader(new
java.io.InputStreamReader(getStream));
while ((bufferStr=myReader.readLine())!=null ){
out.println(bufferStr);//分别把读入的每一块数据送给浏览器处理！
}

这段程序在我开发工具（jdeveloper）中运行没错。放到内网的服务器上报以下错误 。请各位指点。

native.sms.sohu.com
这个名字在你用来部署的哪个内网服务器上能解析么？ |
