Updating Web.xml and Dispatch-servlet.xml

Before running the app, you need to setup the web.xml, dispatcher-servlet.xml and other property files properly. Let’s update the web.xml file by right-click src/main/webapp/WEB-INF/web.xml => Open With Text Editor and then update with below settings:

<?xml version=”1.0″ encoding=”UTF-8″?>

<web-app xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xmlns=”http://java.sun.com/xml/ns/javaee” xmlns:web=”http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd” xsi:schemaLocation=”http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd” id=”WebApp_ID” version=”2.5″>

       <display-name>SpringMVCExample</display-name>

       <welcome-file-list>

       <welcome-file>index.html</welcome-file>

       <welcome-file>index.htm</welcome-file>

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

       <welcome-file>default.html</welcome-file>

       <welcome-file>default.htm</welcome-file>

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

       </welcome-file-list>

       <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>/</url-pattern>

       </servlet-mapping>

</web-app>

Note : <url-pattern>/</url-pattern>

       /      means “all incoming requests”

       /*     it will force the incoming requests going through servlet

Under src/main/webapp/WEB-INF/, right-click to create a new file called dispatcher-servlet.xml with below settings:

<beans xmlns=”http://www.springframework.org/schema/beans”

       xmlns:context=”http://www.springframework.org/schema/context”

       xmlns:mvc=”http://www.springframework.org/schema/mvc”

       xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”

       xsi:schemaLocation=”
