  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-mapping>

        <servlet-name>welcome</servlet-name>

        <url-pattern>/*</url-pattern>

    </servlet-mapping>

     

    <welcome-file-list>

        <welcome-file>welcome.jsp</welcome-file>
