Can't Change Java Security Settings

I'm trying to run a Java app online (the gotomypc.com universal viewer) using Chromium and the jre package from the AUR. Unfortunately the application is not signed. When I run it I get a popup

Application Blocked by Security Settings

Your security settings have blocked an untrusted application from running

I read that this is due to the new Java version's increased security settings, so I ran jcontrol as root and lowered the security level to medium. Supposedly, "all Java applications will be allowed to run after presenting a security prompt". But it still doesn't work. I've restarted my browser and computer to no effect.

Re: Can't Change Java Security Settings

Try setting it manually:

You can find your java settings in ~/.java/deployment/deployment.properties.

Add this line under the #deployment.properties header:

deployment.security.level=MEDIUM

edit: come to think of it, you probably just need to run jcontrol as your regular user and not as root. Since the settings are stored in your home folder, running it as root would store it for the root user instead.

Re: Can't Change Java Security Settings

Since when is java controlled globally? Why did you run the tool as root?
