Not able to run spring application using XML configuration

I am new to spring, trying to run the Spring application through XML configuration, but i am not getting any error in console. But the application is not running and i am getting the 404 error. I didn't add the servlet-api jar in WEB-INF/lib. Can anyone please help me? Thanks in advance.

    package com.raistudies.action;

    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 HelloWorldAction extends AbstractController {

        @Override
        protected ModelAndView handleRequestInternal(HttpServletRequest arg0,
                HttpServletResponse arg1) throws Exception {
            System.out.println(" helloworld... ");
            ModelAndView mav = new ModelAndView();
            mav.setViewName("hello");
            mav.addObject("helloMessage", "Hello World from My First Spring 3 mvc application with xml configuration...");
            return mav;
        }

    }

hello.jsp - WEB-INF/jsp/

<html>
    <head>
        <title>Hello World with spring 3 MVC XML configuration</title>  
    </head>

        <h1>Welcome! Spring MVC XML configuration is working well</h1>
        ${helloMessage}

Your bean definition of the Action is not correct. You have to define a controller bean with some valid name like: 

<bean name="helloWorldController" class="com.raistudies.action.HelloWorldAction" />

Then you need to add the url mapping definition to your configuration to map requests to the defined controller.

<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="mappings">
        <props>
            <prop key="/hello.htm">helloWorldController</prop>
        </props>
    </property>
</bean>
