Check for existance of JSObject document

Hello,
I made an applet which basically works in conjunction with another third party applet. When my applet loads it starts a Thread which sleeps every second and acts as a listener to the third party applet. The problem is that sometimes my applet loads before the other applet can even begin loading which sends an error when it trys to communicate with it.
I have gotten around the problem by having my "listener" thread sleep for a few seconds upon loading, but i feel like this isnt the best solution.
Is there a way to check to see if an applet/document exists? i've tried: public void run() { JSObject window = JSObject.getWindow(this); if (window.evaI("document.applet") == null) { //run code if applet exists } else { //dont run code }

But it doesn't work. It compiles fine, but i get an error everytime my applet loads before the other one can. Any suggestions? Thanks.

Is that JavaScript code? If yes, please note that JavaScript is something completely different than Java, even though the names of those two programming languages have similar names.

You'd probably get more useful answers if you ask the question in a forum about JavaScript instead of Java. Also, on which browser are you trying to run this?

Hi,
Well i guess you'd say that is Java code using Javascript through JSObject. I'm running it on IE.
