Question : DNS mapping

I have a java struts web application running in Oracle Application Server 10.1.2. From the local machine, we normally type http://localhost:8080/ApplicationName to access the application. I want to configure it such that when I type www.abc.com, it should be directed to the home page. The domain www.abc.com is already in use, we want to create a sub domain www.xyz.abc.com to access the application. How to achieve this scenario?

Answer : DNS mapping
