I am trying to create a JavaFX program, and every time I try to run my code I am getting an exception - I'm not entirely sure what it means though...

My code:

package application;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;


public class Main extends Application {
@Override
   public void start(Stage stage) throws Exception {
    Parent root = FXMLLoader.load(getClass().getResource("DogFinderFXML.fxml"));

    Scene scene = new Scene(root);

    stage.setScene(scene);
    stage.setTitle("HelloSwingNode Sample");
    stage.show();
}

/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    launch(args);
}

}

Stack trace:

Any help will be appreciated,
