Java VM Identification

[lagerplease]

I've got a web page which includes a Java applet. Some of my visitors are complaining that when they visit the site the applet doesn't load and simply displays a blank box. I've found out that this is because they haven't got a Java VM installed by default.

Bearing in mind that the majority of my visitors know little about the technicalities of Internet Explorer and other browers is there a way to determine whether or not the VM is installed and suppress the code accordingly via the scripts which invoke the applet in the first place?

I suggested trying here to see if there was a way of detecting the presence of a JVM using JS within the context of a browser.

Check out this thread that I found using a simple google search:

http://forum.java.sun.com/thread.jspa?threadID=168544

It looks like they provide code (and several pages of discussion) that will do as you ask.

Cheers,

Thanks Jeff/Dan. I'll try a few experiments and let you know how I get on.
