Hi Denis,
Do you want the second application to display continuously the data?
(as opposed to update it)
I'm not sure to understand your question. The second application show
the result, computed by another one in background, to the user (when he
open a new session). The user can update data too. I need to show the
most recent data computed by the another app or other instance inside
the session.
You can simply invalidate the objects after some interval, so that the
displayed data is always fresh.
I'm not sure about invalidates objects because of his cost (database
performance) and I don't know exactly how to choose the best interval.
But maybe its the best way to go.
Thanks!
Jacky

Hi,
Can I use the CHNotificationFrameworks in Servlet deployment mode?
I'm not sure if I want to go with JMS servers, if they're still
lacking
and I can have to deploy my application on different platform (RH
Linux
and OS X). I don't want to support different JMS servers.
Is a Notification Frameworks is the only solution (and the best for
me)? What are the other way to accomplish the same goal?
Take an example: 2 different applications (more than 1 instance of
each app) using the same DB, one working in backgound and the other
display data in the DB computed by the other; when a users session is
opened, the data can be modified by any instance of applications
(including by the one running in background).

I already use EOEditingContext.setDefaultFetchTimestampLag() and its
not enough, because data can change while the session is open.
Thanks!
