# Web Application --> Configuration --> Descriptor

Tasks Related Topics Attributes

## Overview

In the Connector Component > Configuration > Descriptor tab, you define the configuration of the application deployment descriptor file that is associated with this Web application module.

This release of WebLogic Server has deprecated the Administration Console Deployment Descriptor Editor. A new Descriptor tab in the Administration Console has replaced it. Using the Descriptor tab, you can view, modify, and persist deployment descriptor elements to the descriptor file within the Web application in the same manner that they were persisted using the Deployment Descriptor Editor.

However, these descriptor elements takes place dynamically at runtime without requiring the Web application to be redeployed. The descriptor elelements contained in the Descriptor tab are limited to only those descriptor elements that may be dynamically changed at runtime.

Note: These attributes are maintained in the weblogic.xml deployment descriptor file. (For more information, refer to weblogic.xml in Developing Web Applications for WebLogic Server.) If you alter the value of any of these attributes and select Apply, then the Web Application deployment descriptor file is updated and deployed to all of the appropriate server machines.
