Session replication is not working as expected in Red Hat JBoss Enterprise Application Platform - Version 6.3.0.GA

I'm bit new to JBoss, could you please help me out in finding the root cause in the below mentioned issue.Thanks and much appreciated,

Issue: Session replication is not happening between master(domain controller) and slave(host). Following are the logs,

From master:

I'm advertising my cluster and i can see the both master and slave nodes are present in the UI, https://10.78.X.X:8445/mod_cluster_manager,

I have disabled firewall and SELinux to avoid network problems.I believe, i have made all the required configurations in domain.xml and ssl.conf of httpd. I have also added <distributable/> tag and jboss-web.xml changes in my war. It'd be of more help if anyone of you direct me in a different direction as i'm totally lost,

Even i can see the following in my master log:

[Host Controller] 07:18:58,862 INFO  [org.jboss.as.domain] (Host Controller Service Threads - 28) JBAS010918: Registered remote slave host "slave", JBoss EAP 6.3.0.GA (AS 7.4.0.Final-redhat-19)
[Server:server-three] 07:18:59,029 INFO  [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (ServerService Thread Pool -- 69) ISPN000094: Received new cluster view: [master:server-three/web|0] [master:server-three/web]

I have tried adding ProxyPass with stickySession, didn't get much luck. any suggestion or help will be much appreciated,

Thanks, Joy.

The <distributable/> tag must be added to the web.xml file not in jboss-web.xml

Enable Session Replication in Your Application

Overview
To take advantage of the JBoss Enterprise Application Platform's High Availability (HA) > features, configure your application to be distributable. This procedure shows how to do that, and then explains some of the advanced configuration options you can use.

  1. Required: Indicate that your application is distributable.

If your application is not marked as distributable, its sessions will never be distributed. Add the <distributable /> element inside the <web-app> tag of your application's web.xml discriptor file. Here is an example. 

<web-app  xmlns="http://java.sun.com/xml/ns/j2ee"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
          xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
                              http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" 
          version="2.4">

      <distributable/>

</web-app>
