mod_cluster is implemented as a core AS 7 module, which is a part of the distribution and, on the httpd side, as a set of libraries installed on the Apache web server.
On the JBoss AS 7 side, you can find already bundled the mod cluster's 1.1.3 module as part of the clustered configuration file. You can find it either in the
standalone-ha.xml file or in the
domain.xml configuration file:
<subsystem xmlns="urn:jboss:domain:modcluster:1.0"> <mod-cluster-config advertise-socket="modcluster"/> </subsystem>
