Question

Как загрузить файл af xml в borderPane ?? Я пытаюсь загрузить его вот так, и он не работает, вы можете увидеть ошибку. Я получаю под кодом

FXMLLoader loader2 = new FXMLLoader();
    path = getClass().getResource("CompanyHome.fxml");
    try {
    loader2.setLocation(path);            
    //whiteBorderPane = (BorderPane) loader2.load();
    whiteBorderPane.setCenter(loader2.load());
    } catch (IOException e){
        System.out.println("Not found: " + path);
        e.printStackTrace();
    }
