Hi!
The following applet (quite sketchily written) reads a file from the
document base and displays its contents..
BTW, I imagine that when you wrote "my site", you are referring to the
host from which the Applet is loaded. Otherwise I do not think that it
is possible to to read a file on some other machine.
Hope this helps...
Cheers
