Please confirm or deny my image/idea: mod_cluster is configured by <Listener className="org.jboss.modcluster.container.catalina.standalone.ModClusterListener" advertise="true"/>
it has nothing to do with session replication, session replication cannot be configured in <Listener/> tag, if we want session replication with ModClusterListener, we must add into <Engine> <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"> - it gives us session replication in mod_cluster (in addition we must add <distributable/> into web.xml - as with any other session replication) regards Jakub
