        try {
            Thread.sleep(2000);
        } catch (InterruptedException ex) {
            Logger.getLogger(CreateSplashScreen.class.getName()).log(Level.SEVERE, null, ex);

Why are you creating an internal JWindow when your class CreateSplashScreen already extends JWindow? There is no need of it. You are messing with your program.

How? You are actually viewing the inner JWindow by jw.setVisible(true); but you are painting the image in the CreateSplashScreen's `JWindow.

Try this code :

public class CreateSplashScreen extends JWindow 
{
    ImageIcon i = new ImageIcon(getClass().getResource("/createsplashscreen/testImage.png"));
    
    public CreateSplashScreen() {
     setSize(700, 500);
     setLocationRelativeTo(null);
     setVisible(true);
    }

    @Override
    public void paint(Graphics g) {
     super.paint(g);
     g.drawImage(i.getImage(), 0, 0, null);
    }

    public void CloseSplashScreen() {
     setVisible(false);
    }
    
    public static void main(String[] args) {
        CreateSplashScreen sp = new CreateSplashScreen();
        try {
            Thread.sleep(2000);
        } catch (InterruptedException ex) {
            
        }
        sp.CloseSplashScreen();
    }    
}

Note: I do not know about your method to fetch image resource from the source folder.

Edit: Assuming that the name of the package containing your class CreateSplashScreen is createsplashscreen, make sure that the image testImage.png is present in the createsplashscreen package of your project.

@Peter For error code, I deleted one line that I added in mamifest.mf file and build a program... This time, didn't give me an error, weird... I was following error code when I got it and it led me to something like "CLASSPATH" section of application generated code... sorry I can't remember exactly Really appreciate Peter for your help. Wish you luck...
