The prefix "beans" for element "beans:beans" is not bound

I am trying to add CSS and JS to JSP page in a spring MVC project so that I have included the reference of js/css folder in dispatcher-servlet.xml as below:

<?xml  version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"

    <beans:bean id="sessionFactory"

                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
    </beans:bean>

    <beans:bean id="reportDAO" class="com.asurion.dao.ReportDaoImpl"></beans:bean>
    <beans:bean id="reportManager" class="com.asurion.service.ReportManagerImpl"></beans:bean>

    <tx:annotation-driven />
    <beans:bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </beans:bean>

</beans:beans>

But it is showing "The prefix "beans" for element "beans:beans" is not bound" in spring configuration file itself so can anyone help me out on this?
