Re: [PHP] Using PHP to determine if user has Java installed

I would think that if you put an <applet> in the page with some public property or method which you could then query from JavaScript if it succeeds it means you do have Java, not only installed but available and enabled to the browser, then you could either send a AJAX message to the server or navigate to some other page. The client might still have Java but not enabled for the browser though and this test would fail. The Java applet itself might communicate to the server but then you wouldn't be able to do much with that page as I don't believe an applet has that much control over the page it resides in.

Subject: [PHP] Using PHP to determine if user has Java installed

Hey List,

I want to know if it is possible to use PHP to find out if a visitor has
Java Runtime Environment installed on a computer. Is there a way to use PHP
to find this similiar to how PHP can be used to find out browser info?
Thanks in advance for your help.

-Matt Livingston
