i recieve that error when i run the code in console but you have created an applet here not an application. so you will need to run the appletviewer to see the results. i personally havent tryed it but i think that is what the problem is. you could try adding the .class to an help webpage and then opening he html page in your browser and see if it shows it and see what happens. i could be wrong but give it a try and see what happens.

ok i was correct. cause i got it to work fine for me. here is what i did.
i created an html doc with the following code in it. and then opened it up

this will make your applet work perfectly good luck

Yup. Appletviewer should do the trick.
