I use maven to develop the application. We can choose any web application to deploy on web logic cluster, any way our aim is to configure web logic cluster and we will go though all over the steps next. 2) Configure cluster domain It's very easy to setup and configure cluster on web logic. Just start Configuration wizard and select customize installation. Change port number of the Admin server, in my case it is 7002 On Configure Managed server page add two new managed server
