Java: Application Blocked by Security Setting

Question

I have a web application that uses Java 6 update 22 and was working fine until yesterday and now all of sudden when I try to load a form from my application it says "Application Blocked by Security Setting" I can't update to the latest Java b/c it's not compatible and I can't set the Java security setting to Medium from high since it is a risk. I have multiple users experiencing this issue, any ideas? I know Windows released their updates recently and not sure if that could be a factor as I couldn't find anything, thanks.

Answer 1

If changing the security level to medium doesn't help you can go to the Windows Control Panel -> Programs -> Java. There you go to Security and press Edit Site List..., click Add and there you type in the location (the URL where the app is hosted) and press OK.

Answer 2

Just set the Java security level to medium or better whitelist your Java app. Here is how to do it.
