Have set the required properties in app, jvmRoute etc..

The log shows this

16:46:03,810 INFO  [JvmRouteBinderValve] JvmRouteBinderValve started
16:46:04,175 INFO  [DeltaManager] Register manager
/servlet-examples-cluster to cluster element unknown with name
16:46:04,176 INFO  [DeltaManager] Starting clustering manager at
16:46:04,176 INFO  [DeltaManager] Manager [/servlet-examples-cluster]:
skipping state transfer. No members active in cluster group.

Does this message mean something is not correct.
16:46:04,176 INFO  [DeltaManager] Manager [/servlet-examples-cluster]:
skipping state transfer. No members active in cluster group.

I still get only 1 value replicated.
