 JApplet is a class and not an interface. You cannot implement a class but you only implement the interface. You have to change your code: public class PrintReceipt extends JFrame implements JApplet to public class PrintReceipt extends JApplet and it will work. The JApplet itself extends java.awt.Panel and you can use it as you would use a JFrame.

  Hope it helps.

hi girionis ,

Thanks for your immediate detailed explanation.

frame.pack();
setTitle("Point of Sales - Receipt");

Some other doubts - for applets, am I not suppose to use these 2 methods?

Thanks.

Dawn.

 You cannot use the pack() method with a JApplet. pack() is inherited from java.awt.Window and since JApplet does not extend it you cannot use it. You could always write yor own though if you feel it is necessary. If you want to set a size for your applet you can use the resize(int, int) or resize(Dimension).

  As for the title, you cannot set the title of the whole window since the applet is running within a browser and it would require you to change the title of the browser. If you want to set a title to your applet window only pass it through the parameters in the HTMl file: <param name="title" value="WStar Applet by Propix">

  Hope it helps.
