By default ActiveMQ uses the $ACTIVEMQ_HOME/data folder. The persistence adapter typically writes into $ACTIVEMQ_HOME/data/kahadb, whereas non-persistent msgs may potentially be written to $ACTIVEMQ_HOME/data/tmp.
Queue properties are also defined in the brokers config, e.g. etc/activemq.xml. Hope this helps. Torsten Mielke tors...@fusesource.com tmie...@blogspot.com
