JavaFX FXML：加载后空白WebView

When I try to load any html or urls using webEngine.load(); my webView is just blank. From what I have read here "JavaFX 2.2 WebView" it seems like I will have to sign my application to let it run outside of sandbox mode. http://docs.oracle.com/javafx/2/deployment/deploy_overview.htm#CEGJGHDA

当我尝试使用webEngine.load()加载任何html或url时;我的webView只是空白。从我在这里阅读的“JavaFX 2.2 WebView”看来,我似乎必须签署我的应用程序才能让它在沙盒模式之外运行。 http://docs.oracle.com/javafx/2/deployment/deploy_overview.htm#CEGJGHDA

Is that what is causing this problem?

是什么导致了这个问题?

I am using NetBeans 8.1, and under Project Settings I am running it as Standalone. I have been following these tutorials and each has gone well. http://docs.oracle.com/javase/8/javafx/get-started-tutorial/get_start_apps.htm#JFXST804

我使用的是NetBeans 8.1,在Project Settings下我将它作为Standalone运行。我一直在关注这些教程,每个教程都很顺利。 http://docs.oracle.com/javase/8/javafx/get-started-tutorial/get_start_apps.htm#JFXST804

Here are my three files.

You haven't specified a controller in your FXML, so the initialize method of the controller is never executed.

您尚未在FXML中指定控制器,因此永远不会执行控制器的初始化方法。

Add the following attribute definition to the VBox element that forms the root element of your FXML:

将以下属性定义添加到构成FXML根元素的VBox元素:

fx:controller="twitchauthorize.FXMLTwitchAuthorizeController"
