From Navigator javaEnabled(): var x = "Java Enabled: " + navigator.javaEnabled();

The result of x will be: Java Enabled: false

I tried jqplugin and deployJava first, but those did fail for IE8 at least. So i came over this lib, that has the most comprehensive documentation and implementation that i could find and worked for all the browser that i could test

Use deployJava.js to check the java installation.

Java/Sun/Oracle provides a deployment toolkit script in the form of a JavaScript file that lets you achieve what you need.

You could invoke the getJREs() function which returns an array of currently-installed JRE version strings.

You can even install a particular JRE version if you need to, via the installJRE(requestVersion) function.
