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: 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.
