GIFs in package resources in JAR

Question

Hello all,
I am deploying a java GUI with resource GIFS in a JAR.
While I am developing in the IDE (Eclipse) everything works out fine: the resource GIFS are loaded from the package resources and are displayed in the GUI.
Then I distribute a JAR using Ant: see manifest.mf at the end of the text.
When I deploy the application now, no resource GIFS are displayed on the GUI. This behaviour changes non-deterministically.
Error could be the packaging into JAR or display of the GUI?
Thank you in advance,
Gerrit Leder

When I loaded the Image with getImage(...) I used checkImage(...):
In the IDE the Result was 0.
Then I loaded the Image with getImage(...) and used prepareImage(...) and then checkImage(....):
In the IDE the result was 7 then 39.
In the Jar the result was 64.
What is the int code representing?
Here is my code now:
class ViewComponent extends JComponent
     private Image image;
     private int iResult;//checkImage: Result
     private boolean bResult;//prepareImage: Result
     protected void paintComponent( Graphics g )
          // Dimension size = this.getSize();
          this.setLocation(35,0);
          if (image.getWidth(this) <= 0 ){
               this.setSize(16,16);
          } else {
               this.setSize(image.getWidth( this), image.getHeight(this ) );
          if ( image != null ){
               g.drawImage( image, 0, 0, this );
               // System.out.println( "paintComponent: width = " + image.getWidth( this) + ", height = " + image.getHeight(this ) );
     public void setImage( String filename )
          image = Toolkit.getDefaultToolkit().getImage( filename );
          System.out.println( "filename >" + filename + "<: width = " + image.getWidth( this) + ", height = " + image.getHeight(this ) );
          if ( image != null )
               bResult=prepareImage(image,
                    image.getWidth(this),
                    image.getHeight(this),
                    this);
               iResult=checkImage(image,
                    image.getWidth(this),
                    image.getHeight(this),
                    this);
          System.out.println("BEFORE repaint(), checkImage Result: " + Integer.toString(iResult));
               repaint();
               iResult=checkImage(image,
                    image.getWidth(this),
                    image.getHeight(this),
                    this);
          System.out.println("AFTER repaint(), checkImage Result: " + Integer.toString(iResult));
}
