Chat Server help... outside IP adress error

Question

In a program i am working on, whenever i replace the ip address to bind to from InetAddress.getLocalHost(); to InetAdress.getByName(">> REAL OUTSIDE IP IN HERE<<"); and run the program i get these errors...
exception in acceptNewConnections()
exception in run()
What can i do to fix this? some code attached
    private void acceptNewConnections() {
     try {
         SocketChannel clientChannel;
         // since sSockChan is non-blocking, this will return immediately
         // regardless of whether there is a connection available
         while ((clientChannel = sSockChan.accept()) != null) {
          addNewClient(clientChannel);
          log.info("got connection from: " + clientChannel.socket().getInetAddress());
          sendBroadcastMessage("login from: " + clientChannel.socket().getInetAddress(), clientChannel);
          sendMessage(clientChannel, "\n\nWelcome to ChatterBox, there are " +
                   clients.size() + " users online.\n");
          sendMessage(clientChannel, "Type 'quit' to exit.\n");
     catch (IOException ioe) {
         log.warn("error during accept(): ", ioe);
     catch (Exception e) {
         log.error("exception in acceptNewConnections()", e);
    public void run() {
     initServerSocket();
     log.info("ChatterServer running");
     running = true;
     int numReady = 0;
     // block while we wait for a client to connect
     while (running) {
         // check for new client connections
         acceptNewConnections();
         // check for incoming mesgs
         readIncomingMessages();
         // sleep a bit
         try {
          Thread.sleep(100);
         catch (InterruptedException ie) {
    }

Additional Code....
    private void initServerSocket() {
     try {
         // open a non-blocking server socket channel
         sSockChan = ServerSocketChannel.open();
         sSockChan.configureBlocking(false);
         // bind to localhost on designated port
         InetAddress addr = InetAddress.getByName("You think i'd give my ip address?");
         sSockChan.socket().bind(new InetSocketAddress(addr, PORT));
         // get a selector for multiplexing the client channels
         readSelector = Selector.open();
     catch (Exception e) {
         log.error("error initializing server", e);
    }
