Błąd przy tworzeniu obrazka png

Witam, mam problem z wyświetleniem obrazka w MIDlecie. Oto kod:

package hello;

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;


public class Midlet extends MIDlet {
    
    public Midlet(){
        disp = Display.getDisplay(this);
        ekran = new Ekran();
        
    }

    public void startApp() {
        disp.setCurrent(ekran);
    }
    
    public void pauseApp() {
    }
    
    public void destroyApp(boolean unconditional) {
    }
    
  
    private Display disp;
    private Ekran ekran;
    
    private class Ekran extends Canvas{
        
        public Ekran(){
            
            try{
          
            obrazek = Image.createImage("/mtbadge-small.gif");
            }
            catch(Exception e){
            e.printStackTrace();
                
            }
            
        }
    
       
        public void paint(Graphics g){
            g.setColor(255, 255, 255);
            g.fillRect(0, 0, 400, 400);
            g.setColor(0, 0, 0);
            g.drawImage(obrazek, 0, 0, Graphics.TOP);
            
        }       
  
        private Image obrazek;
    }
}

Pracuje w NetBeansie (na Win7), obrazek png znajduje się w katalogu "res", próbowałem zmieniać ściężkę dostępu na "/res/mtbadge-small.gif" i nic nie pomagało. Dodam, że na Eclipse miałem podobny problem z wyświetlaniem obrazków (tam jednak pomogło posługiwanie sie bufferedimage, w Java ME niestety to niemożliwe).
