A lot of older KVM-Over-IP interfaces relied on the separately installed Java code base to let users control source computers remotely over a Web Browser. Java has now been deprecated in most modern web browsers, and will no longer function within them. A lot of newer KVM-Over-IP switches instead utilize JavaScript to allow users to control source computers via a HTTP Web Browser. JavaScript is natively built into modern web browsers and does not require any separate software to be installed.
Note: While "Java" and "JavaScript" share the name, in reality they are very different code bases.
