Hi guys,

I've made an application in JavaFX and I do want to export it into a runnable jar.
When I run it from Eclipse or Netbeans, it works well.
But when I run it from windows as an executable jar I get this error for my layout.

Exception in Application start method

My code looks like this on the 47'th line loader.setLocation(getClass().getResource("../application/view/RootLayout.fxml"));

private void initRootLayout() {
    try {
        // Load root layout from fxml file.
        FXMLLoader loader = new FXMLLoader();
        loader.setLocation(getClass().getResource("../application/view/RootLayout.fxml"));
        rootLayout = (BorderPane) loader.load();
        // Show the scene containing the root layout
        Scene scene = new Scene(rootLayout);
        //scene.getStylesheets().add("application/application.css");
        primaryStage.setScene(scene);
        primaryStage.show();

    } catch(IOException e) {
        e.printStackTrace();
    }
}

Are you sure the .fxml file is in the correct directory structure inside your jar?
