Hie,
In which cases, or on what basis is then an EJB solution appropriate. Is
there a list or some evaluation criteria. If there is, i would like to know
as it will guide us in this area

Er ... let me clarify. I've chosen to use EJB for all sorts of reasons.
We have a complex data model to represent our problem-domain, and a mess of
business-logic to manipulate it. We currently have a bunch of servlets that
implement business logic, presentation and data access (via JDBC). My plan
is
to move the business logic into Session Beans, and most of the data-access
into
Entity Beans, leaving the servlets to do presentation/control. I could
perhaps
do this separation without EJB, but then I'd have to implement my own
transactional persistence layer.
So, while the change-scheduling requirement is an important part of the
application, it's by no means the only part. I was just wondering if we
could
use EJBs to solve the scheduling problem.
Based on the feedback I've received, it seems that it might be most
appropriate
to have a stand-alone Java thread that runs the scheduling engine.
