I have noted that when marking a web app as distributable in the wars web.xml in Jboss ver. 4.2 I loose the jboss.web:type=manager in jmx-console for that particular war. I typically collect and store session statistics for an individual war. I am not sure how I can get at this information with session replication enabled, and if loosing access to the manager is expected behavior?
I did find I can get at the replicated session information using jboss.cache TomcatClusteringCache and invoking (print details) this does not provide the session information such as active session counts, rejected, expired, etc that I typically collect.
