How to check (on website) if Java is installed on system (*not* in browser)

I have a Java desktop application, and a website where users can download the .jar file.

I would like to have a button on the website that the user can click to check if the application will run on his computer (i.e. does he have the correct version of Java installed on his system).

Please note that I am not trying to check if Java is enabled in the browser (as deployJava.js will do), but instead to check if it is installed on his system.

My users are not very tech-savvy, and I hope to make this as easy as possible.

Thanks for your help.

There is no way to do this via JavaScript. A better solution would be to use a system specific jar launcher that checks if Java is installed and then either installs/launches the java prorgam or outputs an error message.
