Initially, the server configuration includes an AJP connector suitable for exchanging messages with a load balancing service. See Configuring a remote Apache HTTP server for more information about the HTTP server configuration.
Deploying your application to a cluster
To deploy your application to a cluster and make sure HTTP sessions are replicated successfully, cluster configuration elements of Tomcat Web containers must be configured using GBean definitions within deployment plans.
If you want to deploy your Web application to a cluster, install your WAR files to the appropriate cluster member, assuring that you use the correct deployment plan for each member. Here is the template for your Web application deployment plan
