How to change the runtime name of an application when deploying it via the admin console ?

Issue

• When I deploy a WAR file via management console and change the runtime name to different name, the servlet and context-root is not set so that I cannot access the application.
• Servlet & context-root is not recognised when deploying an application via admin console.
• The context root is not set as per the runtime name given while deploying the application via the admin console.
