xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<display-name>Welcom Example in Spring MVC
</display-name>

<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.
servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.bean</url-pattern>
</servlet-mapping>

<context-param>
<param-name>contextConfigLocation
</param-name>
<param-value>
/WEB-INF/dispatcher-servlet.xml

</context-param>

<listener>
<listener-class>org.springframework.web.context.
ContextLoaderListener</listener-class>
</listener>

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

</web-app>

<beans xmlns=
"http://www.springframework.org/schema/beans"
xmlns:xsi=
"http://www.w3.org/2001/XMLSchema-instance" 
xmlns:context=
"http://www.springframework.org/schema/context"
xsi:schemaLocation=
"http://www.springframework.org/schema/beans 
http://www.springframework.
org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.
org/schema/context/spring-context-2.5.xsd">

<bean id="viewResolver"
class="org.springframework.web.servlet.view.
InternalResourceViewResolver">
<property name="prefix">
<value>/WEB-INF/pages/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>

<bean name="/welcome.bean" 
class="com.r4r.WelcomeController"/>
</beans>

Step 3: Create WelcomeController.java


package com.r4r;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.
servlet.mvc.AbstractController;
public class WelcomeController extends AbstractController {
public ModelAndView handleRequestInternal
(HttpServletRequest request, HttpServletResponse response) {
ModelAndView model = new ModelAndView("WelcomePage");
model.addObject("msg", "Welcome, Mukund Singh R4R.co.in ");
return model;
	}
}

<%@ taglib prefix="c" 
uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<body>
<h1>Out Put</h1>

<H3>${msg}</H3>
