Jboss session replication : Failed to setup clustering, clustering disabled

Question

I am trying to add clustering to my application which uses Jboss server. For replication session, I have added <distributable/> tag in web.xml. But, I get following warning and session replication seems to be not working. Please suggest the best way to handle session replication for Jboss.

Warning: Failed to setup clustering, clustering disabled. NoClassDefFoundError: org/jboss/cache/pojo/jmx/PojoCacheJmxWrapperMBean

Server : Jboss 5.1 Load balance implemented by mod_jk.

Answer 1

Is it possible that you are not using a JBoss profile that has clustering related services? I believe the "default" profile does not have the clustering capabilities. You have to use the "all" profile to have the clustering capabilities.

   |  |---> all  <== (clustering enabled)
