[infinispan-dev] Infinispan Persistence Manager and JBoss Messaging Journal

[Clebert Suconic]

yes.. .the Journal is not a DB.
You have method to recover the state on load. but you need to keep the 
data yourself outside of the Journal on the HashMaps.


The Journal is a way to make your memory persistent.

I thought this was the case for Infinispan. Maybe I missed something 
when reading the code.
