Why am I getting an InvocationTargetException with my JavaFX code?

Question

I'm having trouble with getting a JavaFX media player to work. I am getting an error message saying java.lang.reflect.InvocationTargetException. I researched this error message and found a post that said that I am calling 2 different classes with the same name. However I can't find what classes they are.

Does anyone have any experience with this? I think the message is only used with the JavaFx API. Here is the code:

import java.io.File;
import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.beans.property.DoubleProperty;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
import javafx.scene.paint.Color;
import javafx.stage.Stage;

public class Broadcaster extends Application 
{

public static void main(String[] args) 
{
    launch(args);
}



@Override
  public void start(Stage primaryStage) {
    String workingDir = System.getProperty("C:/Users/Tito/Desktop");
    final File f = new File(workingDir, "Jeremy.wmv");

    final Media m = new Media(f.toURI().toString());
    final MediaPlayer mp = new MediaPlayer(m);
    final MediaView mv = new MediaView(mp);

    final DoubleProperty width = mv.fitWidthProperty();
    final DoubleProperty height = mv.fitHeightProperty();

    width.bind(Bindings.selectDouble(mv.sceneProperty(), "width"));
    height.bind(Bindings.selectDouble(mv.sceneProperty(), "height")); 



    mv.setPreserveRatio(true);

    StackPane root = new StackPane();
    root.getChildren().add(mv);

    final Scene scene = new Scene(root, 960, 540);
    scene.setFill(Color.BLACK);

    primaryStage.setScene(scene);
    primaryStage.setTitle("Full Screen Video Player");
    primaryStage.setFullScreen(true);
    primaryStage.show();

    mp.play();
  }
}

The problem was my file location. For some reason the code isn't looking for the file in String workingDir = System.getProperty("C:/Users/Tito/Desktop"); It's looking for it in C:\Users\Tito\eclipse-workspace\Broadcast. I have to find out why. When I moved the media file to C:\Users\Tito\eclipse-workspace\Broadcast, it played the audio, but not the video.
