asp.net - How can I detect the Java runtime installed on a client from an ASP .NET website? -

I have an ASP .NET website that hosts Java Applet. Java Applet requires Java Runtime version 1.6 Update 11.

How can I find that the client has a proper runtime so that I can display an informational message, if they do not?

Edit: The solution platform must be independent.
