IE or Netscape don't support directly Swing Applet. You must use the Java plugins. Then you will need to use the <OBJECT> (IE) or <EMBED> (Netscape) HTML tag instead of the regular <APPLET> tag. To be able use Swing classes (without download delay) from Netscape, copy Swing JAR files (swingall.jar) in the PLUGINS directory and restart Netscape. This is ok with pre-Java 2 Swing. With that version you need the Java plug-in to be able to use the swing classes.
