Java Blocks Application From Running With An Insecure Or Expired JRE

Well, seems Java’s runtime environment has gotten more strict as new versions of it came out. When you load an applet and you get this message

java.lang.SecurityException: Your security settings have blocked an application from running with an insecure or expired jre.

There is only one solution as a user to make the applet run. You will have to lower the security settings in your Java settings.

Go to Control Panel then open Java icon. Go to security tab and set the security setting to medium. That should run the applet.

Just be sure you trust the publisher or else your PC will be at risk. This is the only solution possible since the other way is to wait for the publisher of the applet to repackage the jar file with manifest attributes that will enable the latest Java runtime environment to run the applet.

  1. There is definitely a second option too. If you know and trust the website whose applet is being forced stop by Java Security, do the following without compromising with level of security. Open the java control panel through Program>Java>Configure Java and click ‘Security’ tab. Under Security tab you will notice this option ‘Exception Site List’. Click ‘Edit Site List’ button and add the full address of website whose applet you trust and want to run. Press okay and you are done.
