Re: Thread question
Supporting it from the server would be nice. The alternative of having a
cron job executing a script that fires up a client that initiates the
process is not very pretty IMHO.
If I understand it correctly there is nothing in the 1.1 spec that forces an
EJB appserver to support scheduled execution of object methods but most
seems to have support for it. I know that for JBoss it is done as part of
JMX with a MBean to register the object that is using the
javax.management.timer.Timer class and others classes in javax.management.
SilverStream uses a proprietary component they call "Scheduled Business
Objects" that does the same thing (what to invoke and when)
