I have a 3rd party digital signature Java applet that is having issue on "some" client computers, I know how to verify the version but . 
<p>I wish I had more specifics, I don't have browser or java versions of the client computers having issues. As it stands right now I have a java applet that just checks the version if the client clicks it. Is there a way to check version before the page loads? I'd rather be proactive than reactive on the page. I've checked documentation <a href="http://download.oracle.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html" rel="nofollow">here</a> but without having access to the digital signature applet code, am having trouble wrapping my head around it.</p>
