How do I call an applet method using javascript and the sun applet plug-in?

I am using JSObject to communicate between applets and javascript and this is working fine.

Indeed I have seen examples on the internet of calling an applet method using javascript when the applet is embedded in the HTML using the applet tag.

What I cannot find anywhere is how to call an applet method using javascript when the applet is embedded in the HTML using the sun plug-in (i.e. the object tag)
