Help... Urgent.. PLEASE... Applet Code....

[sam patel]

Hi,
I am kind of new to java...
I found this JApplet code which writes text to a image file...But i want to run this without using the applet...How can i covert this JApplet to an old fashion java Application...
I would appreciate if someone can show me how... I am posting the code below.....You will need JAI API...
Thanks in advance....

setBackground(Color.white);
String fileName = DEFAULT_FILE;
// Read the image from the designated path.
System.out.println("load image from '" + fileName+"'");
img = (RenderedImage)JAI.create("fileload", fileName);
}

public void paint(Graphics g) {

Dimension d = getSize();
g2.setBackground(getBackground());

}

} catch (Exception ex) {

}

}

public static void main(String argv[]) {

demo.init();
JFrame f = new JFrame("JAI Demo - JPEGJai");
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
});
f.getContentPane().add("Center", demo);
f.pack();
f.setSize(new Dimension(400,300));
f.show();
}
}
