As someone who has had a deal of experience
with applets, I can only add that Ed got it
'spot on'.

If you wish to have more control over the
deployment of the applet, I recommend you
look to launching it using Java web start
(JWS). Here is an exmaple of JWS to launch
an applet (and an application)
<http://www.physci.org/jws/#jtest>

Note that although this is an HTML/applet
question, I would also recommend ..
comp.lang.java.help
...or..
comp.lang.java.programmer
...for any Java related questions (though do
not mistake Java programmers for people who
can write valid and robust HTML or JS!).
