Probleme avec web.xml (spring security)

Bonjour,

Je voudrai implémenter spring security dans mon application jee, et quand je declare les filtres et le listener spring dans web.xml, l'application ne marche plus!
(j'utilise spring 2 et spring security 3.1.0 RELEASE)

voici web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
  classpath:application-context.xml
    </param-value>
 </context-param>

        <filter>
		<filter-name>springSecurityFilterChain</filter-name>
		<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
	</filter>
 
	<filter-mapping>
		<filter-name>springSecurityFilterChain</filter-name>
		<url-pattern>/*</url-pattern>
        </filter-mapping>
<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
 

application-context.xml:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:util="http://www.springframework.org/schema/util"
	xmlns:security="http://www.springframework.org/schema/security"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
                           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
                           http://www.springframework.org/schema/util 
                           http://www.springframework.org/schema/util/spring-util-3.0.xsd
                           http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-2.0.xsd">
</beans>

je reçois l'erreur suivante :
GRAVE: Exception au démarrage du filtre springSecurityFilterChain
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'springSecurityFilterChain' is defined
