Are you writing applets with Java Swing and need a way to determine whether or not your potential users have Swing installed and working properly?

You don't seem to have Java enabled. Please enable it and reload this page.

If the user has Java Swing installed in their browser, they will see a message saying: You Have Swing (user configurable) and the applet will turn into a link to another webpage (user configurable).

If the user does not have Java Swing installed they will be presented with a user configurable button that will take them to a page that gives instructions on how to get Java Swing installed in their browser.
