How can I make my JApplet automatically download the Java Plug-in needed to run Swing applets?

Sun provides an HTML Converter tool (http://java.sun.com/products/plugin/1.2/converter.html) that will setup your web pages to include code that will cause the Java Plug-in to be needed to use the applet. When the browser loads this page, it will go through its normal means of installing an ActiveX control (for Internet Explorer) or Netscape Plug-in for Communicator. By itself, the JApplet cannot force the download of the Plug-in.

For 1.3 and 1.4, you don't need the converter. Just install the latest version of the Java Plugin and your all set.
