Deshalb möchte ich so die Szene zwischen zwei FXML Dateien wechseln, aber ich bekomme diese Fehlermeldung, wenn ich versuche, die Anwendung zu starten:Fehler Schalt Szenen mit FXML

Exception running application survey.Main
ich verschiedene Ansätze versucht, die FXML-Datei zu laden, aber jedes Mal tritt derselbe Fehler auf. Ich habe auch versucht, mehrere möglichen von der Gemeinschaft vorgeschlagenen Lösungen hier aber keiner scheint zu meinem Problem zu beheben. Die meisten von ihnen sagten, dass es eine Frage des richtigen Weges sein würde, aber ich genau denselben Weg in der Steuerung wie in dem Haupt-App laden und ohne handleButtonAction() in der Steuerung der Anwendungen richtig beginnen. Ich stehe jetzt stundenlang an dieser grundlegenden Aufgabe fest. Ich benutze IDEA und hier ist mein Code:
Main:
package survey;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
import java.io.IOException;
public class Main extends Application {
private Stage primaryStage;
private BorderPane rootLayout;
@Override
public void start(Stage primaryStage) throws Exception{
this.primaryStage = primaryStage;
this.primaryStage.setTitle("Modul A");
initRootlayout();
showModuleA();
}
private void initRootlayout() throws IOException{
FXMLLoader loader = new FXMLLoader();
loader.setLocation(Main.class.getResource("view/rootLayout.fxml"));
rootLayout = loader.load();
Scene scene = new Scene(rootLayout);
primaryStage.setScene(scene);
primaryStage.show();
}
private void showModuleA() throws IOException {
FXMLLoader loader = new FXMLLoader();
loader.setLocation(Main.class.getResource("view/moduleA.fxml"));
AnchorPane rootPane = loader.load();
rootLayout.setCenter(rootPane);
}
public static void main(String[] args) {
launch(args);
}
}
Controller:
package survey.view;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.fxml.Initializable;
import javafx.scene.Parent;

import javafx.scene.control.Button;
import javafx.stage.Stage;
import java.awt.event.ActionEvent;
import java.io.IOException;
import java.net.URL;
import java.util.ResourceBundle;
public class moduleAController implements Initializable {
@FXML private Button bBack;
@FXML private Button bForward;
@FXML
private void handleButtonAction(ActionEvent event) throws IOException{
Stage stage;
Parent root;
if (event.getSource() == bBack){
stage = (Stage) bBack.getScene().getWindow();
root = FXMLLoader.load(getClass().getResource("view/moduleB.fxml"));
} else {
stage = (Stage) bForward.getScene().getWindow();
root = FXMLLoader.load(getClass().getResource("view/moduleA.fxml"));
}
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}

ich jede Hilfe dankbar. Danke im Voraus!
EDIT: Neben der falschen Import von Event Action haben einen Fehler auf dem Weg war. Der Regler ist in der Ansicht Ordner so ist der Weg nur moduleB.fxml nicht view/moduleB.fxml.
Danke für die Hilfe!
Oh mein Gott, du hast Recht! Vielen Dank. Aber da war tatsächlich ein weiterer Fehler. Der Controller befindet sich nicht im Hauptordner, sondern im Ansichtsordner. So war der Pfad neben dem falschen Import des ActionEvent falsch. – jeypeu
