ha mo, Martin Honnen, Constants,

In NN3+ and IE4+ APPLET elements are reflected into js as elements of 
the
  document.applets
array and as properties of the document object if they are named, i.e. 
an
  <APPLET NAME="anApplet" ...>...</APPLET>
is scriptable as
  document.anApplet
and 
  document.applets[appletIndexInSouce]
Then you can access public members with the usual dot or bracket 
notation for properties/methods:
  document.anApplet.publicProperty
  document.anApplet.publicMethod()
or
  document.anApplet['publicProperty']
  document.anApplet['publicMethod']()
where the last notation is important for member names like delete which 
are keywors in js for instance the java.io.File class has a delete 
method you would need to call as
  fileObj['delete']()

Details about parameter passing/type conversion between JavaScript and 
Java when calling into an applet are explained in the liveconnect 
section of the client side JavaScript guide on developer.netscape.com.

If you use sun's java plugin (so an EMBED tag in NN4 and an OBJECT tag 
in IE) you can with IE call
  document.all.objectID.methodName()
NN4 with the java plugin DOES NOT ALLOW JavaScript to call the EMBEDded 
applet's methods.
