最近搞了简单的webservice，总是报错，求指点 ?报错

运行client端时总报错

报错为：
Exception in thread "main" java.net.ConnectException: Connection refused: connect

以下是代码：

server:
ServerSocket ss = new ServerSocket(80);

Socket s = ss.accept();
InputStream is = s.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is));

           System.out.println("client"+br.readLine());

            br.close();
            is.close();
            s.close();

client:
Socket s = new Socket("192.168.1.104",80);
OutputStream os = s.getOutputStream();

BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(os));
bw.write("hello ");

            bw.close();
            os.close();
            s.close();

高手指点一哈
