    Default Stuck on socketChannel.read();

    I have an applet that connects to a C/C++ server.

    The server sends packets but the applet can't read them for some reason.

    It gets stuck on socketChannel.read(); even though I set it to non-blocking.

                try
                {
                    socketChannel = SocketChannel.open();
                    socketChannel.configureBlocking(false);
                    socketChannel.connect(new InetSocketAddress(serverAddress, serverPort));
                }
                catch (UnknownHostException e) 
                {
                    message = "Don't know about host: " + serverAddress;
                    return;
                } 
                catch (IOException e) 
                {
                    message = "Couldn't get I/O for the connection to: " + serverAddress;
                    return;
                }
     
                try
                {
                    while(!socketChannel.finishConnect());
                }
                catch(IOException e)
                {
                    message = "Error on finishConnect();";
                    return;
                }
     
                try
                {
                    socketChannel.socket().setTcpNoDelay(true);
                }
                catch(SocketException e)
                {
                    message = "Error: " + e.toString();
                    return;
                }
     
                message = "Logging in...";
     
                int bytes;
     
     
                try 
                {
                    response.clear();
                    bytes = socketChannel.read(response); // <------- here
                }
                catch (IOException e) 
                {
                    message = "Exception: " + e.getMessage();
                    return;
                }
     
                message = "Done";

    don't understand what you mean with "It gets stuck on socketChannel.read();". Exception? Hung? Garbage?
