HTML event if applet can't load?

Hi,

I'm using the OBJECT tag to deploy an applet, and I have setup the classid field to require a specific version of the Sun JVM to be used to run the applet.
If the client does not have this version installed, is there some event that is triggered that I can detect in my Javascript or JSP code? I tried using the onerror event, but this event is not triggered if the client doesn't have the right JVM version.
