Question

I'm trying to setup Http Session Replication based on WSO2 AS cluster (v5.3.0).
but it doesn't work . (guide: https://docs.wso2.com/display/AS520/Clustering+and+Http+Session+Replication)
Any one can help?
Here is the stack trace for the error:

Here is catalina-server.xml config
<Cluster className="org.wso2.carbon.core.session.CarbonTomcatSimpleTcpCluster"/>
<Valve className="org.wso2.carbon.tomcat.ext.valves.CarbonTomcatSessionReplicationValve"/>
And added <distributable/> in my web.xml file

You have to use following valve
<Valve className="org.wso2.carbon.webapp.mgt.session.CarbonTomcatSessionReplicationValve"/>
instead of
<Valve className="org.wso2.carbon.tomcat.ext.valves.CarbonTomcatSessionReplicationValve"/>
It's documented Enabling HTTP Session Replication
