Intelligent Refresh/Reloading
Chaps
I have a list of records that are displayed on a web page, the database
receives new records periodically, is there a way to determine when a new
record is loaded into the dB and then using Struts reload that page when a
new record is added?
Regards
Jason

No.
The webserver has no way of notifying the client that it needs to load the
page again.
Struts doesnt provide anything to help with this.
Some attempted solutions Ive seen include the good old polling method (js
causes the page to reaload every minute or so) which is inefficient and
inelegant, and 'pushlets' which are an evil hack where the server doesnt
close the connection to the client (tying up a socket), and can write lines
of javascript to the connection occasionally causing the client to do stuff.
Neither are very robust.
One might also consider the idea of an applet that maintains its own
connection with the server but Ive not implemented such a thing myself.
