Need to know version of Java on user PC



Have a games website which uses java. To weed out people with no java
I put an applet (aTicker, if anyone knows it) which scrolls the phrase
"Java is working fine" on the registration page. And instructions
telling them what to do if they can't see the phrase scroll by.

A third party has developed a new puzzle to sit on our site. Many
people who play the game everyday (and can see the scrolling) click on
puzzle link and are told that something is not right with their java.
I (person of decent developer skills but very little knowledge of
Java) have been entrusted to get to the bottom of it. The puzzle is
written in 1.6 and my first guess is that everything is a version
issue.

I would like to start by knowing if there is an applet out there that
can tell me the version of Java running on a user's PC. Basically I
want to be able to put the info from http://www.java.com/en/download/help/testvm.xml
onto my test page.

thanks,
.
