✔ JavaFX Anwendung exportieren

[jimb0p]

Hallo Zusammen,

ich habe eine JavaFX Anwendung geschrieben welche auch fehlerfrei läuft in eclipse. Wenn ich Sie nun als Runnable Jar Exportiere und per java -jar name.jar ausführe bekomme ich folgende Fehlermeldung:

Exception in Application start method

Die Zeilen die Dort erwähnt werden sind folgende:

public void initRootLayout() {
        try {
            // Load root layout from fxml file.
            FXMLLoader loader = new FXMLLoader();
            loader.setLocation(MainApp.class.getResource("../view/RootLayout.fxml"));
            rootLayout = (BorderPane) loader.load();

            // Show the scene containing the root layout.
            Scene scene = new Scene(rootLayout);
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

Was genau habe ich falsch gemacht?

Gruß!

Konnte es selbst herausfinden. Das Problem lag an Zeile fünf "../view/RootLayout.fxml" hier musste der komplette Pfad angegeben werden. Also "/de/blabla/view/RootLayout.fxml" wichtig ist hierbei der erste Slash!
