pom.xml
-------------

           <artifactId>junit</artifactId>
           <version>3.8.1</version>
           <scope>test</scope>
       </dependency>

       <!-- Servlet Library -->

  So   need   to  configure   web.xml .  This  needed  when your   create   web  using jsp , servlets ets

   you can use   simplest   formate  also  for this application.

 web.xml
--------
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"


         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
         http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
           <display-name>StartWeb</display-name>
         
    <servlet>
        <servlet-name>welcome</servlet-name>
        <servlet-class>/welcome.jsp</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>welcome</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
     
    <welcome-file-list>
        <welcome-file>welcome.jsp</welcome-file>
    </welcome-file-list>    

</web-app>



 welcome.jsp
--------------


<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
