What is a deployment descriptor?

Deployment descriptor is a configuration file for the web application and it’s name is web.xml and it resides in WEB-INF directory. Servlet container use this file to configure web application servlets, servlet config params, context init params, filters, listeners, welcome pages and error handlers.
With servlet 3.0 annotations, we can remove a lot of clutter from web.xml by configuring servlets, filters and listeners using annotations.
