It does break the spec, bottom line is it is going to be passivated and your
thing probably won't work,
the best thing is to build a "timer" service in the server. It is something
that I have been looking at for a long time and never thought through.
We would need a generic way of specifying a schedule of events (punctual,
recuring, intervals, special dates etc etc) we would register along with a
set of instances to be called. We would also need the way to tell the
server "here register these keys or handles with this timer event"....
In short, EJB is probably not your answer if you are looking for something
quick and dirty. A long term solution to this "timed execution" problem is
something you might want to look at in jboss.
