Off-topic -- how can I get the client browser resolution in servlet?

Hi,

Since the XMLC/barracuda users can adjust the image sizes, or even use 
different images, easily based on the client's browser resolution, if 
known, I am asking this to the Barracuda mailing list, hoping some one 
may have done this before.
   
In javascript the following code provides the resolution height and width:

    var SCRwidth  = window.screen.width;
    var SCRheight = window.screen.height;

How can I get the same thing in Java?  Any java, or barracuda, classes  
for this purpose?

Any pointers would be highly appreciated.

With regards,

Damar
