I thinlk it has to be

To get more information with applet errors, open your systems’s Control Panel and start the Java Control Panel. Go to the Advanced Tab and activate the Java Console.
After changing this one line i still have in progress bar this message: Error: Unable to start Lesson07. I activated console and i have this message:

You can’t just start an arbitrary class as applet. It has to be a subclass of Applet and implement the applet’s lifecylcle methods to do sensible stuff.
See http://java.sun.com/docs/books/tutorial/deployment/applet/index.html
Cylab thank you for help. That’s web information should clear my mind (i think ;P).
