If you have deployed and accessed your application, go to the jboss.cache:service=TomcatClusteringCache MBean and invoke the printDetails operation. You should see output resembling the following.

/JSESSION

/localhost

/quote

VERSION: 6

This output shows two separate web sessions, in one application named quote , that are being shared via JBossCache. This example uses a replication-granularity of session. Had ATTRIBUTE level replication been used, there would be additional entries showing each replicated session attribute. In either case, the replicated values are stored in an opaque MarshelledValue container. There aren't currently any tools that allow you to inspect the contents of the replicated session values. If you do not see any output, either the application was not correctly marked as distributable or you haven't accessed a part of application that places values in the HTTP session. The org.jboss.cache and org.jboss.web logging categories provide additional insight into session replication useful for debugging purposes.
