Oracle finally added one major feature to Java that had been missing, the ability to whitelist sites. Now, admins can control which sites run java, what security level the apps run at, and even what version of Java the site will use. It does work pretty well, but it is not easy to set up and administer.
To set up the deployment rule set, which gives you all these new features, you need to create an xml file, turn it into a jar file, sign the jar file with a trusted certificate in a java keystore, and then deploy the file to your environment. Easy, right? Well I’ll go through all the steps you will need to follow to get this up and running in your environment!
