enter image description here package LinLab_System;

import javafx.application.Application; import javafx.fxml.FXMLLoader; import javafx.scene.Scene; import javafx.scene.image.Image; import javafx.stage.Stage; import java.net.URL; public class Main extends Application { private static Scene initialWindow; static Scene settings; public static Stage prStage; @Override public void start(Stage primaryStage) throws Exception{ prStage=primaryStage; URL ur = getClass().getResource("Initial_window.fxml"); initialWindow=new Scene(FXMLLoader.load(ur), 900, 600); settings=new Scene(FXMLLoader.load(getClass().getResource("settings/settings.fxml")), 280, 270); primaryStage.setTitle("LinLab System (LLS)"); primaryStage.setScene(initialWindow); primaryStage.getIcons().add(new Image("file:src/LinLab_System/images/Logo.jpg")); primaryStage.setResizable(false); primaryStage.show(); } public static void main(String[] args) { launch(args); } }

Created an artifact from this project and tried to launch the resulting jarnik. In IntellijIdea 16 everything works, but when I try to launch .jar it gives an error.

This is a bug report.

How exactly is the link to the file in the project?

    Get the resource as a stream:
    InputStream stream = getClass().getResourceAsStream("Initial_window.fxml");
    and then pass it to the new FXMLLoader().load(stream) method new FXMLLoader().load(stream)

    • Displays this: Error: (21, 43) java: non-static method <T> load (java.io.InputStream) cannot be referenced from a static context - Dmitry Lin
    • initialWindow=new Scene(FXMLLoader.load(getClass().getResourceAsStream("Initial_window.fxml")), 900, 600); - Dmitry Lin
    • I apologize, now I will correct it - I looked at javadoc, did not notice that load is not static - Sergi
    • @DmitryLin corrected the answer - Sergi
    • You're welcome, just remember to close stream with try-with-resources. - Sergi
