Hello experts,

I have two questions.  

1- when the window pops up for someone that says "Doyou want to install and run Java Plug-in 1.4.2" is there a way whether someone clicked "yes" or "no"?  

2- is there a way to tell if someone logged into your site has it installed or not?

Thanks,
kesea

and 3- can you do voice chat with the old AWT technology? Or just with the new swing?

1) I am not sure what you mean. I have never seen this window since I always have the JRE installed. Can you elaborate a bit?
2) You can do it if you use javascript: http://www.skyzyx.com/scripts/java.php
3) Voice chat does not have to do with AWT. It can work independently.

One way would be to use a 1.4 feature and then get a response from the user based on its correct execution

Load an small applet that requires the plugin, if its not installed it will not load.

You can see an example of this technique used at:

AWT/Swing handle the GUI so are not really voice related.

"Load an small applet that requires the plugin, if its not installed it will not load"

This is the solution that worked for me.

unless you happen to be sitting with them client-side as they try to load it or tell them to do something like email you with the result, whereas the one i gave, which is a functional superset of that 'answer', will

So you can produce a list of client-sides that have tried to load your applet in the last n days and failed can you?

Just waiting (and still waiting) for somebody to show me how the answer is correct, and *without* rummaging through server log files. I am quite willing to be proved wrong
