  public static void main(final String[] args) throws Exception {
    final TaskClient client = new TaskClient(new MinaTaskClientConnector("SampleClient", new MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));

    if (client.connect("localhost", 9123)) {
      final BlockingQueryGenericResponseHandler handler = new BlockingQueryGenericResponseHandler();

      client.query("SELECT t.taskData.comments FROM Task t WHERE t.id = 1", Integer.MAX_VALUE, 0, handler);

      for (final Object result : handler.getResults())
