3)failed to setup clustering", what does it mean?

  [jbosscacheservice][main] jboss.cache:service=tomcatclusteringcache service to tomcat clustering not found

  [jbosscachemanager][main] jbosscacheservice to tomcat clustering not found

  [tomcatdeployer][main] failed to setup clustering, clustering disabled

there's two possibilities here:

1) since 3.2.6, http session replication is based on , and more precisely the service.in 3.2.6, 3.2.7, 4.0.1 and 4.0.1sp1, the dependency on this service is missing in tomcat's jboss-service.xml. to fix it, please edit /all/deploy/jbossweb-tomcat5x.sar/meta-inf/jboss-service.xml and enable the ?"> element, update the mbean as well as the element itself.

the resulting code should look as follows:

      jboss.cache:service=tomcatclusteringcache

instead of

2) this error could also come up if you're trying to remove the clustering capabilities from the all configuration as explained in . even though you might have modified jbossweb-tomcat5x.sar/meta-inf/jboss-service.xml to remove the dependency on

jboss.cache:service=tomcatclusteringcache

, if the web application is deployed as

, as will try starting up

jboss.cache:service=tomcatclusteringcache

, for http session replication. in this case, the error message should not be considered as a failure because if it can't start it up, it'll log the error but will continue working as normal.
