Developing java applets in Domino Designer

I am developing a java applet containing a JTable swing component to allow users to edit multiple value fields in the NotesDocument.

I have written and compiled the java code in Eclipse and then I’ve created a java applet on a Form in Domino Designer with this class-file.

I was wondering if there was an option to write this applet directly in Domino Designer on Eclipse.

Does anyone know how this can be done?
