I am following this tutorial to get into JavaFX using scene builder and so far I really like it as the person who made it explains things in deep detail. I finished the first part and tried executing the code so far, but it returns multiple errors. Here is more information about the project.
The project is based on Model-View-Controller structure, therefore, I have the following packages -slavi.address.controllerslavi.address.viewslavi.address.model
The view package, contains 2 files, 1 for Root Layout and 1 with the application layout(pretty basic app).
The files in it are PersonOverview.fxml and RootLayout.fxml
In the controller package I have the following file(Provided by the tutorial)
package slavi.address.controller;
import java.io.IOException;
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;
public class MainApp extends Application {
private Stage primaryStage;
private BorderPane rootLayout;
@Override
public void start(Stage primaryStage) {
this.primaryStage = primaryStage;
this.primaryStage.setTitle("AddressApp");
try {
// Load the root layout from the fxml file
FXMLLoader loader = new FXMLLoader(MainApp.class.getResource("view/RootLayout.fxml"));
rootLayout = (BorderPane) loader.load();
Scene scene = new Scene(rootLayout);
primaryStage.setScene(scene);
primaryStage.show();
} catch (IOException e) {
// Exception gets thrown if the fxml file could not be loaded
e.printStackTrace();
}
showPersonOverview();
}
/**
* Returns the main stage.
* @return
*/
public Stage getPrimaryStage() {
return primaryStage;
}
/**
* Shows the person overview scene.
*/
public void showPersonOverview() {
try {
// Load the fxml file and set into the center of the main layout
FXMLLoader loader = new FXMLLoader(MainApp.class.getResource("view/PersonOverview.fxml"));
AnchorPane overviewPage = (AnchorPane) loader.load();
rootLayout.setCenter(overviewPage);
} catch (IOException e) {
// Exception gets thrown if the fxml file could not be loaded
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
The errors I get are the following:

Exception running application application.Main
I think there is something wrong with the provided path as well, because on the tutorial instead of slavi.address.controller they suggest slavi.address
