    protected static final String LOCALHOST = "127.0.0.1";
    
    protected ExchangeServer server;
    
    protected ExchangeChannel client;
    
    protected WorldHandler handler = new WorldHandler();
    
    protected abstract ExchangeServer newServer(int port, Replier<?> receiver) throws RemotingException;
    
    protected abstract ExchangeChannel newClient(int port) throws RemotingException;
    
    @Override
    protected void setUp() throws Exception {
        super.setUp();
        int port = (int) (1000 * Math.random() + 10000);
        server = newServer(port, handler);
        client = newClient(port);
    }

    @Override
    protected void tearDown() throws Exception {
        super.tearDown();
        try {
            if (server != null)

            if (client != null)
                client.close();
        }

    @Test
    public void testFuture() throws Exception {
        ResponseFuture future = client.request(new World("world"));
        Hello result = (Hello)future.get();
