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

你是不是贴错了
ServerSocket是服务器端，Socket是客户端。
程序中有错误，你试试下面的代码看行不行
服务器端：
ServerSocket server = new ServerSocket(1044);
Socket s = serveraccept();//等待客户端连接
BufferedReader br=new BufferedReader(new InputStream( sgetInputStream()));
File f=new File("testtmp");
BufferedWriter bw=new BufferedWriter(new FileWriter(f));
String str=brreadLine();
while(str!=null)
{bwwrite(str);
bwclose();
brclose();
}
Systemoutprintln("已接收到的信息，并保存在临时文件中
");
客户端：
BufferedReader br=new BufferedReader(new FileReader(filename));//filename为文件对象
String serverIP = "127001";//服务器IP地址
Systemoutprintln("正在连接服务器，请稍候");
Socket s = new Socket(serverIP,1044); Systemoutprintln("已正确连接到显示服务端，开始传输信息");
BufferedWriter bw=new BufferedWriter(new OutputStream(new sgetOutputStream()));
代码不是太完整，也未编译。你可以参照其中部分，再对你的程序进行修改，希望对你有所帮助！
