Applets are small programs (usually written in Java) which can run in 
your web browser, and are often used to avoid some of the limitations 
of normal html pages - allowing the authors to do fancy things with 
graphics, buttons etc. Applets normally run with a reduced set of 
privileges (called a sandbox) - they can only talk to the server that 
you downloaded the applet from (the website you were viewing), and 
shouldn't be able to make any changes to your system, so are relatively 
safe.

The applet on this page is a bit different. It's a signed applet. When 
you first loaded it you would have seen a pop-up asking if you 
"trusted" the applet. Accepting the default "yes, I trust it" will give 
the applet many more privileges (the same privileges as the user you 
loaded it as), so it can access local files, and contact any remote 
server it wishes to. Make sure you really do trust an applet before you 
agree to "trust" it - think of it like "do you wish to run this 
application" on Windows.

Signed applets are normaly needed for one of two reasons:

1) The applet needs access to local resources

2) The applet needs to contact servers online other than the one from 
which you loaded it.

In the case of 1), seeing as you stated that the site was IE oriented, 
the functionality requiring access to local resources probably wouldn't 
work under linux

In the case of 2), it won't work when you're not connected to the 
internet.

If you trust this applet, and want to try to run it offline, you could 
try downloading the archive containing the applet, from:

http://www.worldcupchart.com/wcup.jar

and saving it in the same directory as you saved the html page. This 
might work, but I can't verify it as I don't trust the applet, sorry.

And they ask you to turn off  some security features...

Hope that helps.
