No, there's no documentation on 5.0 yet. If you add a jvmRoute in server.xml, the server will assume "UseJK" is true as global default. So, typically no need to set it. The global default can be overridden on a per-webapp basis in jboss-web.xml: | <replication-config> | <use-jk>false</use-jk> | </replication-config> | You can also force the setting of the global default rather than relying on the presence/absence of a jvmRoute. Uncomment the following in server/all/deployers/jbossweb.deployer/META-INF/wer-deployers-beans.xml's WebAppClusteringDefaultsDeployer: | <!-- | <property name="useJK">false</property> | --> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4133494#...
