Subject Re: In Memory Message store will be 0 when the source files get updated.
Date Wed, 25 Jul 2012 15:14:05 GMT
In the InMemory Message Store Stored Messages are associated with the
MessageStore Object itself. So in case of a Server restart/ Config re-load
that messages will be lost as It will create new Configuration Object/s.

For the persistence behavior the ideal solution is to have a Persistent
Message Store (ex : JMS MessageStore  DBMessage Store etc..)
