Java stopped running unsigned applications one day.

Your security settings have blocked an untrusted application from running.

Java security useless error message

The documentation states that I can add a site to an exception list to get around this problem. However, I am trying to run a Java applet for WebSDR usage, and there are many sites with many applets needed. It's a real hassle to have to do this, especially when I'm using Chrome and it already prompts me before running Java at all.

Java has become almost completely useless to me, and I'd like to fix that by toning down the security a bit. Is it possible to either disable the blocking of unsigned apps, or add a wildcard of URLs to the exception list? I've tried adding * or http://, but the "Configure Java" panel won't except either of these.

This can be controlled by the Java Control Panel Applet. You will require administrator rights to change the setting. –  Ramhound Feb 12 at 3:35
Why was this downvoted? –  Brad Feb 12 at 13:38
@Ramhound I have used that applet, and there is no setting on it I can find to allow unsigned apps. –  Brad Feb 12 at 13:39

Go to the Java Control Panel. In the Security Tab put the security to Medium and if the applet is not signed but doesn't require full permissions it should run. If it needs full permissions. This will prompt you for continuing. See details here: http://www.java.com/en/download/help/jcp_security.xml

As for Chrome if you enter in chrome://plugins under Java plugin settings you can also set "always allow" not to see the prompt.

I tried "medium", but the app must be requesting full permissions as I still get prompted. –  Brad Feb 12 at 13:37
Right...The prompts are by design at that level of security –  Ramhound Feb 12 at 13:45
Medium was removed in Java 8. Any workaround? –  Quantum7 Nov 4 at 12:15
