Hi Filip, Thanks for your prompt response. I added an attribute to the ServletContext object in one instance and tried to access the same attribute in another instance and it returns null.
The <Cluster> (in server.xml) element has the attribute managerClassName=org.apache.catalina.cluster.session.DeltaManager ? Or org.apache.catalina.session.PersistentReplicationManager is required to be set? Do you want to see my server.xml files and code? Thank you again.
