How do I show a JavaFX webview when I click on a Menu item?

In my application I want the user user to be able to click on a menu item and have a new window appear. However, when I run my code it says that you can open a new window from a menu item. So my question is,is there another work around or another simpler way for me to accomplish my goal. Thanks for your help.

P.S --> I had posted a similar question earlier, but had made a mistake in copying the correct code I had. This is the correct error and code I get.

Code:

    /**
 * When the Logger menu item is clicked, then it will execute and make a new window
 * @param actionEvent
 * @throws Exception
 */
public void clickedLoggerMenu(ActionEvent actionEvent) throws Exception {
    //The name of the controller
    FXMLLoader loader = new FXMLLoader(getClass().getResource("/fxml/viewer_logger.fxml"));
    Parent home_page = (Parent) loader.load();

    LoggerController logController = loader.getController();

    //this sets the scene
        Scene home_page_scene = new Scene(home_page, 650, 580);
        Stage app_stage = (Stage) ((Node) actionEvent.getSource()).getScene().getWindow();
        app_stage.setScene(home_page_scene);
        app_stage.show();

}

Exception:

Caused by: java.lang.ClassCastException: [email protected]/javafx.scene.control.MenuItem cannot be cast to [email protected]/javafx.scene.Node
    at controller.SubmitController.clickedLoggerMenu(SubmitController.java:99)

The problem is in how you are trying to create the Stage:

Stage app_stage = (Stage) ((Node) actionEvent.getSource()).getScene().getWindow();

You are trying to cast the MenuItem to a Node and that is not how it works.

You also need to create a new Stage anyway, so do not try to get the original Window.

Stage app_stage = new Stage()

Then build the Scene from there.

Side Note: I recommend reading some good JavaFX tutorials to learn the basics.
