Security exception running applet in coplet

[Jeff Davis]

Hi,

Has any ever tried running a Java applet inside of a coplet? When I run the
coplet page directly as a direct HTML link through Cocoon, my applet runs
fine. However, when I run it within a coplet, I get the following error
message on the Browser's Java console:

Anyone have any ideas? I was planning to use thinlet-based coplets for my
system (www.thinlets.com).

Thanks!
