JavaFX JAVAFX java.lang.reflect.InvocationTargetException

[UchihaSevenfold]

Hiiiiilfe ! ich bin hier nun wirkich am verzweifeln. ich moechte ein programm schreiben mit dem ich ein bild aus flickr downloaden kann und in einem imageview meiner GUI anzeigen. Ich habe hier Code der bei einem komillitonen von mir super duper funktioniert. Nur bei mir kommt ein riesenfehler sobald ich auf den button klicke damit er mir die gewuenschten bilder runterläd. Problem ist der Code ist wirklich 1 zu 1. ich habe nichts anderes gemacht aber irgendwie scheint er probleme zu haben mit dem Controller und der fxml datei oder so ! ich sitze hier nu seit 5 stunden und ich kann einfach nich mehr ;( ich hoffe das mit hier irgendeiner erklären kann was der fehler zu bedeuten hat.

Hier ist mal mein Code der Controller klasse

public class HalloController implements Initializable {
      String apiKey ="7a794d8692936b4b6371ad1750a617d2";
      String secret= "601e153ed7618eb4";
      
    @FXML
    ImageView view;
  
    
    @FXML
    private void ladeFoto(ActionEvent event) throws FlickrException {
         
      
       
        
        Flickr flickr = new Flickr (apiKey, secret , new REST());
        
        SearchParameters searchParams = new SearchParameters();
        String[] tags = new String[]{"Dog","Beagle"};
        
        searchParams.setSort(SearchParameters.INTERESTINGNESS_DESC);
        searchParams.setTags(tags);
     
        
       
        PhotosInterface photoInt = flickr.getPhotosInterface();      
        PhotoList photoList = photoInt.search(searchParams,20,1);
  
        if(photoList!=null){
            for (Iterator it = photoList.iterator(); it.hasNext();) {
                Object photoList1 = it.next();
                Photo ph = (Photo) photoList1;
                String URL = ph.getLargeUrl();
                Image remoteImage = new Image(URL, true);
                view.setImage(remoteImage);
            }
            }
    }
    
    @Override
    public void initialize(URL url, ResourceBundle rb) {
        // TODO
    }    
    
}

Hier die Mainklasse:

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

/**

public class Bild extends Application {
    
    @Override
    public void start(Stage stage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("hallo.fxml"));
        
       
        
       
        
        Scene scene = new Scene(root);
        
        stage.setScene(scene);
        stage.show();
    }

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

hier der error:

Aus dem Log ist ja zu entnehmen das der fehler mit dieser zeile aus der controller klasse zu tunhat

 Flickr flickr = new Flickr (apiKey, secret , new REST());

Er zeigt mir aber komplett keine fehler an. das programm startet und sobald ich auf den button klickekommt der fehler. ich hab schon so viel gegoogelt und rum probiert aber nichts hat geholfen =(

ich hoffe irgendjemand weiss wo der fehler leigen koennte =(

Aus dem Stacktrace :

Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Logger

Ich würde sagen, dass du kein log4j jar File im classpath hast.

Ich hoffe dein API und SECRET-KEY sind nicht die echten, sonst würde ich das im Code noch rausnehmen oder zufallszahlen reinschreiben ;-)
