Hello,
YES, JMS is the right (and standard) way to achieve
your goal !
One solution is to define a JMS Topic, let your clients
be JMS clients, which will be subscribing to the topic.
And then, in your Session Bean, in the method that uses
the entity beans (I imagine within a transaction), also
send a JMS message to the Topic (within the same
transaction, to be sure to send the message if and only if
the database is modified). That's all.
JOnAS provides all what is needed to do that.
Best Regards,
François
