JRE detection on the user's computer

Is there a solution that can be placed at webpage and will detect is
JRE installed or not on user's computer and if not it will execute some
script (JS / PHP) and if yes - it will load an applet?

Currently not all browsers inform user when he open a webpage with an
applet and he does not have JRE on his computer. He just see a blank
space and in many cases - do not know what is that.

It is not the browser's job to inform the end user,
that job is left to the HTML. Here is the appropriate
HTML to keep the end user informed of what they are
supposed to be seeing, and what action to take in
case something fails.


<applet
class='...'
alt='This applet requires Java enabled, see you System
Administrator!'

</applet>
