Solution: It means in your weblogic.xml HTTP session specified but clustering is not enable and you are using standalone server most of the this happens in development environment because here we don’t use multiple server. To fix this issue please comment out below line in your weblogic.xml file:

<!-- <persistent-store-type>replicated</persistent-store-type> -->

 

and your final weblogic.xml file should similar to below:

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app"
                      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
