I have a spring based application in JSP, that checks for new messges using ajax periodically. I want to display an icon in system try (just like outlook) on arrival of new message. Particulalry if browser my web applicaiton is runnign is minimized or not active.

Is there any built in support for this using Spring or other frame work. What could be steps in acheiving this? In desktop applicaiton Java SystemTray class can be used easily but i'm not sure how to do it in web enviornemnt using jsp pages particulalry.

Thanks
