Welcome to JavaRanch.

What happens if you run this code? Are there any error messages, either from JavaScript or from Java?

Not sure what's going on, but LiveConnect (the Java/JavaScript bridge technology) is notoriously fickle. I'd recommend to use the Common DOM API instead, if at all possible.

Hi,

On the first look I'd say that there could be two potential problems in your example/code:

1. I'm not sure, if you're calling the JSObject.getWindow in a right place
As far as I know, you should call it in Applets init() method.
Example:

2. Following code is missing in your HTML:

Hope this helps.



Regards,
Rok
