    InetSocketAddress addr = new InetSocketAddress(host, port);
    SocketChannel sc = SocketChannel.open();
    sc.configureBlocking(false);//from  w w  w . j  av a  2s . co m
    System.out.println("initiating connection");
    sc.connect(addr);
    while (!sc.finishConnect()) {
      doSomethingUseful();
    }
    System.out.println("connection established");
    // Do something with the connected socket
    // The SocketChannel is still nonblocking
