how can I know if an applet is running in a browser vs. invoked from Eclipse

As from subject. How can I determine if the applet is running in the browser? I want to have a mock data provider to do debugging with开发者_开发问答out involving the browser, and neutralize all the LiveConnect calls I have if I'm not in the browser.

Why not add a parameter for use in Eclipse? Read this on init() and if found handle appropriately.

EDIT: Update URL.
