Java Version using Javascript

Copy linkTweet thisAlerts:
Feb 03.2005

Hi,

Is there a way of obtaining the Java version using Javascript? A bit like grabbing the browser name etc. But, this actually checks a users Java level?

I ask, due to the need to be able to offer a ‘lesser’ version of an applet, one without TImerTask and other Java 1.3 bits. Some of my users have out-dated machines or ones that cannot use Sun JVM due to company needs of Microsoft JVM

I have found one link to a script, but it seems to return the same value regardless of versions…

Help gratefully accepted.

Dave

Kor, good idea, but not possible. If the unavailable classes are in the import list, even if not used, as the applet is loaded it will attempt to import them and fail.

I have even commented their use out of the code, so that the imports would never be used, but applet will load all imports regardless. The check needs to be before the applet is loaded....hence this question

If it will work, I will try it, but I know not how to??? Can you point me somewhere?

Cheers for all the reads this thread is getting.
