Java 8 Update 20 Missing security options

Question

I have Java 8 update 20 and I just made my first applet, but when I try to run it in the browser it says that my security settings have blocked it! After I go into my java settings and go in the security tab all I see it:

Enable Java content in the browser (It is a checkbox) Security level for applications not on the Exception site list Very high (RADIO BUTTON) High (RADIO BUTTON)

And then I have my exception site list... I am missing the Medium radio button? I can't run my applet without the medium option! I have tried adding my site to the exceptions list but it didn't work... I have deinstalled the previous version of java which was Java 8 update 11. What's the problem??? Thanks!

Solution

If I understand your question;

I am missing the Medium radio button? ... What's the problem?

Correct. You are missing the Medium radio button now. To quote the 8u20 release notes

Java Control Panel Changes

The Update tab in the Java Control Panel now enables the users to automatically update 64-bit JREs (in addition to 32-bit versions) that are installed on their system.

The Medium security level has been removed. Now only High and Very High levels are available.

You can develop with an applet viewer; you'll need to sign your code for security reasons.

Edit

From Deploying an Applet (The Java Tutorials) -

To deploy your Java applet, first compile the source code, package it as a JAR file, and sign the JAR file.

See Signing JAR Files for how to sign your Applet.
