Tiles 3 with spring MVC 3 integration not working

First time I am trying to integrate Tiles3 with spring MVC 3. My Spring servlet has the following entries:

<bean id="tilesviewResolver" class="org.springframework.web.servlet.view.tiles3.TilesViewResolver" p:order="0"/>  

      <bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">  
           <property name="definitions">  
                <list>  
                     <value>/WEB-INF/tiles.xml</value>  
                </list>  
           </property>  
      </bean> 

The jar files I have in my project's class path are:

commons-beanutils-1.8.0.jar
commons-digester-2.0.jar
commons-lang-2.4.jar
commons-logging-1.0.4.jar

But I am getting the error:

Cannot find class [org.springframework.web.servlet.view.tiles3.TilesConfigurer] for bean with name 'tilesConfigurer' defined in ServletContext resource [/WEB-INF/thinkTank-servlet.xml]; nested exception is java.lang.ClassNotFoundException: org.springframework.web.servlet.view.tiles3.TilesConfigurer

thinkTank-servlet.xml is my spring servlet, can anyone help, what I am doing wrong:

add this snipt in your spring servlet

<beans:bean id="tilesViewResolver"
        class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <beans:property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView" />
    </beans:bean>
    <beans:bean class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
       <beans:property name="definitions">
            <beans:list>
                <beans:value>/WEB-INF/spring/appServlet/views.xml</beans:value>
            </beans:list>
       </beans:property>
</beans:bean>
