If you use the <APPLET> tag it doesn't use the plug-in, it uses the
browser's default JVM, which will not have access to Swing classes.
To use the plug-in you have to use the <OBJECT> tag for IE or the
<EMBED> tag for Netscape instead of <APPLET>. Pretty silly to have two
different browser-dependent tags, huh? There are examples of how to use
these tags, and Javascript examples for when you don't know the type of
browser that will be used to view the page here:
