Detecting if .class is present

[Thomas Magma]

Hello,

I have a case where an applet .class file may or may not be present. In the
case when it is not present I get a big gray box where the applet is suppose
to be. This is understandable, but undesirable when someone is viewing or
printing the page. Is there a way to test first if the .class file is
present before hand in order to avoid the big gray box.

Thanks.

If you have server scripting such as PHP you can. Probably also with
javascript but then it'd be very much dependant on whether your user had
javascript (and enabled).
