Answer 1

Use getResourceAsStream instead :

anchorPane = loader.load(LightView.class.getResourceAsStream(fxmlFile));

Its simple, work well.

Answer 2

In addition to Alf's answer, I want to note, that the code can be shorter:

URL location = getClass().getResource("MyController.fxml");

FXMLLoader fxmlLoader = new FXMLLoader();

Parent root = (Parent) fxmlLoader.load(location.openStream());

This works as well.

Answer 3

I use the following :

URL location = getClass().getResource("MyController.fxml");

FXMLLoader fxmlLoader = new FXMLLoader();
fxmlLoader.setLocation(location);
fxmlLoader.setBuilderFactory(new JavaFXBuilderFactory());

Parent root = (Parent) fxmlLoader.load(location.openStream());

In this way fxmlLoader.getController() is not null

Answer 4

You can try this...

    FXMLLoader loader = new FXMLLoader();
    loader.setLocation(getClass().getResource("LightView.fxml"));
    loader.load();
    Parent parent = loader.getRoot();
    Scene Scene = new Scene(parent);
    Stage Stage = new Stage();
    LightViewController lv = loader.getController();
    lv.setLight(light);
    Stage.setScene(Scene);
    Stage.show();
