    JBOSSCache Node not synchronized

    Vincenzo Certo Vincenzo Newbie

      I've implemented a JbossCache cluster with two nodes distributed on different server. It has a CacheLoader based on oracle.
      When I applied a modification of the cache on one node, it doesn't synchronized the other one. Following there is the xml config I used.
      Where is the problem? For updating the other cluster node, I need to restart the application using it.
