The deployment descriptor also provides configuration information for that web module's deployment. The deployment descriptor takes the form of a plain text file, called web.xml, that is written in the XML (Extensible Markup Language) syntax. The IDE supports both version 2.3 and version 2.4 of the Servlet specifications.
