First let me say that I have no details of what Sun are doing with respect to
integration of EJB and JMS/events/timeout objects (which are like JMS messages,
except that they are delivered at a specified time rather than ASAP, and usually
go back to the sender rather than elsewhere) except that I'm sure it will be
pretty basic.
You are hinting at the need for a broader framework that creates relationships
between stateful session beans, so that for example if one SB terminates another
is informed about it. I designed and built a system like this (not for java
though) a few years ago and it is very powerful because it allows a distributed
object-oriented design that operates naturally on session-oriented data -
something extremely valuable in complex customer-facing applications but not
possible with EJB today or with basic EJB/JMS integration.
So yes, having such a framework would be a good thing - but don't hold your
breath!
