    Session replication failed in jboss cluster

    Zhixing Lv Newbie

      I set up the jboss cluster with two jboss servers.
      Session sticky is successful.
      But Session replication is failed.
      I just looked up the document of
      http://docs.jboss.org/jbossas/jboss4guide/r4/html/cluster.chapt.html

      There were no errors in the log file, and it seems successful.
      But every server maintains it's own session.

      I don't know what's wrong, anyone knows about it?
      Is there anything else I should pay attention in the configuration?

      Thanks a lot.

          b)<jboss_home>\server\all\deploy\jbossweb-tomcat55.sar\META-INF

          false

                Hi,
                You might have missed some configuration changes in the jboss or Apache for session replication...
                Please go through this link to overcome your problem

                http://wiki.jboss.org/wiki/Wiki.jsp?page=UsingMod_jk1.2WithJBoss,

                  I have modified jboss-service.xml and server.xml,
                  attribute name="UseJK" true /attribute
                  Engine name="jboss.web" defaultHost="localhost" jvmRoute="server1"

                  and in the workers2.properties file, I have set worker.loadbalancer.sticky_session to "0":
                  worker.loadbalancer.sticky_session=0

                  My jboss version is 4.0.2 and Apache version is 2.0.55

                  It seems the session isn't be replicated.

                  The following is a part of the log file:
