when does openjms server write messages to the message table?

Hi All,
   Sorry for multiple postings today, on the openjms learning curve.
   I am trying to get a high level of understanding of what the openjms server is doing.  When OpenJms gets a message from a publisher, does it send it right off to the subscribers, or does it write all messages to the message database table and then pull them out in order to deliver them?
   I ask because I am using openJMS and am "losing" some messages, I think that maybe they are stuck in the message table and unable to get out.
Thanks if anyone can provide this kind of info,
Kim

A subscriber only receives messages from the time its subscription became active.
Any message published prior to then is discarded.
If you want to receive messages that were published when the subscriber is inactive,
you need to use a durable suscriber.
