Is there any way for a new subscriber process to receive
messages that have been published to a topic, and already
received by all known subscribers, prior to the new subscriber
starting up for the FIRST time?

In other words, let's
assume that, initially, five subscriber processes registered for a
given topic are up and running. Then, let's assume a critical
persistent message has been published to that topic and is successfully
received by all five subscriber processes. Given the above, my
question is: Is there any way for a brand-spanking new
subscriber process that starts up for the first time (ie. subscriber
number six) to receive the same critical message already
received by the other five subscribers? Since there were only
five known subscribers at the time the message was published,
is the message gone forever once the original five subscribers
received it? If so, is there any way to prevent the message from
being removed from persistent storage so that any potential
new subscribers can receive it? Are there any workarounds to this
issue? Is there any WebLogic 6.0 specific feature that can
accomplish this, using the Administrator Console or some other
way?
