Musachy,
Yes, we use struts 1.x, and I really dont think we can download any of these
external libraries.
So said so, I have to write javascript etc to achive these "AJAX timed
events"..
Any one has done it to achieve it ?
I believe javascript,XML etc are needed.. any examples.

Oops...I can't help it, I always assume we are talking about S2. If you are
using S1, pick an ajax framework, most of them have a Div tag like the one
on S2. See Frank's email for details on one of them.
