Hello;
Regarding A, I was looking at the NotificationFramework of Project
Wonder, but if I red correctly is not really efficient if the
application has a lot of request (I know this one doesn't).
I'm a bit unsure as to why the P.W. change notification would be
inefficient compared to using D.A-s? Listing on a queue server would
have to be at least as efficient as firing requests through the HTTP
adaptor and then the rest would be the same in both cases.
My only project with change notification has a fairly project-
specific arrangement, but more recently I've been doing some work on
a generic solution. This hasn't hit production yet, but it does seem
to work quite well and uses a JMS topic to move the change
notifications around.
cheers.
