Answer / shankar reddy
The web.xml file provides configuration and deployment
information for the Web components that comprise a Web
application. Examples of Web components are servlet
parameters, servlet and JavaServer Pages (JSP) definitions,
and Uniform Resource Locators (URL) mappings.

Answer / deepa vg
The web.xml is called the deployment descriptor. It is used
to provide details about the deployment of the web
application.
At a very minimum, it tells the servlet container the
version of the servlet specifications to use for the app.
Additionally, since you are using servlets, you have to use
it to provide details about the class of your servlets, and
the URL to use for mapping HTTP requests to the servlet.
You also can specify security roles and limited access for
pages, define attributes to store application-wide, define
specific pieces of information for JSPs, define MIME-Type-
Mappings, Welcome Page file names, and other details about
the Servlet Context.
