Answer 1

g7appletDialog is a bit strange:

1. The convention for class names is to use an initial capital letter.
2. The convention is to use packages (directory paths) like de.javamunich.g7applet.MainDialog.

Check the case sensitive correctness of class name and file name. (BTW it is hard to change only the case of a Windows file name in one step.) Maybe you forgot the package name in HTML?

Start afresh with a new sample applet to have valid examples of how to use codebase and other attributes. It must be something simple.

If you can, extend your question with the HTML code for the applet, and where the .class file resides.
