Java plugin in WebKitGTK JVM dialogs - how do I disable?

[Barry Scott]

I want to run java applets in WebKitGTK on Fedora 13.
When I run tightvnc, for example, the JVM pops up a dialog asking
for permission to run the trusted applet.

Since my application has no keyboard or mouse, its a kiosk app, there
is no way to click on the dialog.

What I want to do is configure the system so that it never asks
and assumes yes run the app. How do I do this for all possible applets?
