Can't read a bytebuffer from a DatagramChannel

[darnandy]

I am trying to implement a simple client/server app using a DatagramChannel to pass ByteBuffers. The client seems to connect okay and the number of bytes returned from the write method is correct; however, the server side never seems to receive anything

Server side:

DatagramChannel inchannel;
DatagramSocket ds;
CLIENT_ADDRESS = 5000;

public void runServer() {
   inChannel = DatagramChannel.open();
   ds = inChannel.socket();
   ds.bind(inAddress);
   inChannel.connect(new InetSocketAddress("localhost", CLIENT_ADDRESS);
   ByteBuffer inputBuffer = ByteBuffer.allocate(512); //plenty big enough   

   at this point print statements indicate that the channel is open and connected

   while(true) {
      try {
         if (inChannel.isConnected()) {                          //it is
            inputBuffer.clear();                                     //prep for reading
            SocketAddress sock = inChannel.receive(inputBuffer);
            inputBuffer.flip();
            while (inputBuffer.hasRemaining() ) {
               System.out.println(inputBuffer.get() + " ");
            }
         }
      }
      catch

etc.

I never see anything. Know I'm missing something pretty fundamental but can't understand what it is!!
