高手帮忙看看这段java代码

Question

服务器端代码:
ServerSocket server=null;
        try
        {
            server=new ServerSocket(5432);
        }
        catch(IOException e )
        {
            
        }
        OutputStream os;
        InputStream is;
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); 
        DataOutputStream dos;
        DataInputStream dis;
        Socket s;
        InetAddress address;
        String receiveMsg;
        String sendMsg;
        while(true)
        {
            try
            {
            s=server.accept();
            address=s.getInetAddress();
            System.out.println(address+"已连接");
            os=s.getOutputStream();
            is=s.getInputStream();
            dos=new DataOutputStream(os);
            dis=new DataInputStream(is);
            receiveMsg=new String(dis.readUTF());
            System.out.println("The message from client is:"+receiveMsg);
            System.out.println("What is the message that we will send to the client:");
            sendMsg=br.readLine();
            dos.writeUTF(sendMsg);
            dos.flush();
            }
            catch(IOException e)
            {
                e.printStackTrace();
            }客户端代码;
 Socket s;
        OutputStream os;
        InputStream is;
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); 
        DataOutputStream dos;
        DataInputStream dis;
        String reciveMsg=null;
        String sendMsg=null;
        try
        {
            s=new Socket("127.0.0.1",5432);
            is=s.getInputStream();
            os=s.getOutputStream();
            dos=new DataOutputStream(os);
            dis=new DataInputStream(is);
            System.out.println("Please input the message that will send to the server: ");
            sendMsg=br.readLine();
            dos.writeUTF(sendMsg);
            reciveMsg=dis.readUTF();
            System.out.println("The message from the server is:"+reciveMsg);
            
        }
        catch(IOException e)
        {
            
        }运行会出现异常， receiveMsg=new String(dis.readUTF());就是这句。java.net.SocketException: Connection reset
另外，我用的NetBeans6.0，生成的jar文件运行时没有仿dos界面，看不见想看的东西，能不能调啊

Answer 1

服务器段代码没有贴完整
有可能是在客户端还没有读完毕数据，服务器端就把线路断开了，所以收数据失败。NetBeans6.0没有用过，但是jar一定会有打印输出的，这个和什么生成的没有关系。
你在cmd下用java -jar ×××.jar 来运行看看。
