Overview

A class to install and configure a mod_cluster service in a JBoss profile

Configuration:

:path => where the mod_cluster.sar is located :folder => where the mod_cluster.sar should be installed (default: $JBOSS_HOME/server/$CONFIG/deploy)

The additional configurations are the entries in the bean ModClusterConfig (mod_cluster-jboss-beans.xml) and can be in a String form (using the entry name) or in a Symbol form (using ruby nomenclature - :sticky_session)
