Configuring a software load balancer

Although WebLogic Server is an application server used mostly for dynamic content and Java EE applications, it is also a fully-featured web server that's capable of serving static files as HTML and images. A WebLogic instance can even be used as a load balancer to distribute requests between clustered servers and do the necessary failover routing when a server becomes unavailable. In order to leverage such built-in functionalities, you must set up weblogic.servlet.proxy.HttpClusterServlet to act as your default web application for the domain. Here are the steps:

1. Create a new dynamic web application in Eclipse named HttpClusterServlet.

2. Open or create a web.xml deployment descriptor under the WEB-INF folder.

3. Copy and paste the following content inside web.xml:

   ...
   <servlet>
     <servlet-name>HttpClusterServlet</servlet-name>
     <servlet-class>
       weblogic.servlet.proxy.HttpClusterServlet
     </servlet-class>
     <init-param>
    ...
