Hi,
I have set up a 2 node JBoss-4.0.0 cluster.
I enabled the HTTP session replication by changing the Snapshotmode to instant
in jboss-service.xml .
Also, I made the application distributable.
The startup showed no error.
When I brought down on instance that was serving the request, the request got
forwarded to the next instance, but the session objects were not replicated/
Lost. I didn't get any error messages,though.
However, when I stopped the network for that system, I got following errors--
12:09:24,718 WARN [ReplicationInterceptor] beforeCompletion(): runPreparePhase
failed. Transaction is now rolled back
