Hi, I think the main problem is that each cluster node uses it's own persistence manager (database on localhost). See http://wiki.apache.org/jackrabbit/Clustering "That means all Jackrabbit cluster nodes need access to the SAME persistent storage (persistence manager and data store)." By the way, this is not the case for the file system: "However, each cluster node needs its own (private) FileSystem and Search index."
