Rejecting Security Warning with Signed Applets

I have developed an applet that is similar to a chat program and uses OpenJMS. In its current state, the application recognizes each user by their computer name (example: Robs_Computer). The applet is signed and executes correctly with full permissions. My problem is that if a user rejects the Security Warning (by clicking "No"), the applet still manages to execute. The only difference in execution between accepting and rejecting the signature is the screen name (computer recognition). When the applet is rejected, the application executes and the user is now recognized by the username "localhost" as opposed to "Robs_Computer". The fact that it comes up as localhost is not an issue right now, I am more concerned about the fact that the applet still mangaes to execute. Thanks,

- Rob

If you don't want the applet to execute if the user clicks no on the "do you trust" question.You can try to read user.home for example, if the user clicked no you wont be able to read that system porperty.

The strangest part about this situation is this:

When I deploy to tomcat, which resides on my local pc, everything runs as planned. When the user rejects the warning, the applet does not execute. When I deploy to a Linux Server running tomcat, this is not the case. The applet executes when that warning is rejected.

Any ideas?

Thanks,

Rob
