hello,
I am not sure if I well understand your question. Consequently, I am not
sure if you are on the good ML... ;)
What you want (if I suppress all J2EE buzzwords) is to refresh a web page
asynchronously when a particular event occurs (on the server). Right?
If so, this is definitively not a J2EE problem but rather a browser/HTTP
session problem.
If you want to stay pure HTML, the only thing you can do is to automatically
refresh your page every n seconds. Otherwise, you may use some applet
registering on the server to receive callbacks. Nevertheless, I think (if my
memory serves) that callbacks requires your applet (inbound TCP connection)
to enhance its standard security context in the browser (which is
non-standard with the different browsers on the market...)
Is there a more elegant solution with Javascript and some DHTML? don't
know... maybe
Maybe using an hidden frame which refresh itself every n seconds and only
updates the DHTML content of another visible frame if its new value is
different than the one on the visible frame... Any other idea?
Cheers,
Sacha
