JLabel updating StatusBar

[kellan4459]

I have three classes (StatusBar, ImageGUI, ImageLoader)

the status bar class is nothing more than a JLabel that I instantiate in the ImageLoader class. In this class I update the text of the JLabel throughout the class. I then have my ImageGUI which has an instance of ImageLoader. I add the ImageLoader StatusBar to my GUI through a getStatusBar getter method in ImageLoader. It shows up with the instantiated text but the text doesn't change. It has been a while since I have worked with the Java GUI so I'm a little rusty. Does anyone see what I may be missing?

###STATUS BAR CLASS
public class StatusBar extends JLabel {

/** Creates a new instance of StatusBar */
public StatusBar() {
super();

this.setMessage("Ready");
}

public void setMessage(String message) {
this.setText(message);
}
}


###snippet where I add to my Frame in ImageGUI class
iu = new ImageLoader();
myPanel.add(iu.getStatusBar());

###snippet where I create then method where I set the text ###in ImageLoader class
public class ImageUploader {
private StatusBar sbPoint;

public ImageUploader(){
this.sbPoint = new StatusBar();
this.sbPoint.setMessage("Please select a directory to process");
}

public StatusBar getStatusBar(){

return this.sbPoint;
}

public void AddWatermark(String directoryPath,String imagePath, String watermarkPath) throws IOException {
this.getStatusBar().setMessage("creating WaterMark for "+imagePath);
}


}

I have changed it to get rid of the extra StatusBar class and I'm just using a JLabel in the Gui class with a getter and setter. Now I have the 2 classes and I see the setStatusBar sets the right value and the getStatusBar returns that value. Though I still do not get the update on my JLabel. I have tried repaint and other things but nothing seems to work. Here is my code for both classes. Any help is greatly appreciated.
