如何在Java FX 11中实现JavaFX 2.2示例

Question

我正在尝试使用Eclipse在Java FX 11中实现this示例。

我有4个文件，FXMLTableView.java具有start和main方法，FXMLTableViewController.java（仅具有类声明才为空，fxml_tableview.fxml具有fxml代码。 如上面的链接所示，Person.java具有Person类。 我收到错误消息，当我从fxml中删除此代码（我仅使用一行进行测试）时，程序会运行，但是列中当然没有数据：

<Person firstName="Jacob" lastName="Smith"email="jacob.smith@example.com"/>

任何建议如何解决此问题？

下面是错误代码：
