Making Java GUI code open source?

[celendin]

Hi I am a beginner to Java. I was wondering if this was possible.

Say I write a calculator applet to host on my website for other users to use. Can I make just the GUI code open source so users can modify the appearance of the applet and then save the GUI code to their usernames on the web server, so the next time they logon, the changed calculator appearance will be stored on the web server already. However, the core code should remain the same so new users who sign up won't be using some else's Calculator GUI code.

You can pass parameters from your HTML code to define any aspect of an applet. You could make it so when a user logs in, those values will be recalled from a file, for example.
