I'm not sure if you have tried this but;
Why not create a javascript timer, one that sends a request to a
servlet every few seconds/minutes (depending on your capacity/server
load). In this way the response could give the value of the field you
need.
Ive done something similar in the past, but at a previous company so i
can't copy paste code im afraid. I managed it with the references at
w3schools. Great site that.
Hope that helps,

Hi,
thanks for your replies.>make periodic requests to the server (via AJAX is
Well, thats the point. Assume 5 browsers have established a session
with the web server.
now 1 of them has bid his amount, whcih is, changed the current price
value. THIS, can be posted to the server.Also can be done using AJAX.
However, I would also want to update the rest of the 4 browsers with
the latest update of the price.

The seconds part is what I also thought about; because this is a
auction site and all users got to be updated asap. However, I am

Wont it increase the traffic, slow down the performance and restrict
the number of users I can have ?
I have heard a lot of stock tickers work the same way. Any clue on how
they function ?
thanks
Also look into cometd.
