[Security] Problème de satisfaction de dépendance

Bonjour.
Dans ma webapp (Struts2 + Spring + Acegi + Hibernate)
J'ai l'erreur suivante lors de l'initialisation du contexte de Spring :

Code:

GRAVE: Exception lors de l'envoi de l'évènement contexte initialisé (context initialized) à l'instance de classe d'écoute (listener) org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'logoutFilter' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Unsatisfied dependency expressed through constructor argument with index 1 of type [org.acegisecurity.ui.logout.LogoutHandler[]]: There are 0 beans of type [[Lorg.acegisecurity.ui.logout.LogoutHandler;] available for autowiring: []. There should have been exactly 1 to be able to autowire constructor of bean 'logoutFilter'.

En fait je n'ai fait que reprendre la configuration de l'exemple de base pour Spring :

Code:

	<!-- ACEGI START -->
	<bean id="filterChainProxy" class="org.acegisecurity.util.FilterChainProxy">

				PATTERN_TYPE_APACHE_ANT
				/**=httpSessionContextIntegrationFilter,logoutFilter,authenticationProcessingFilter,securityContextHolderAwareRequestFilter,rememberMeProcessingFilter,anonymousProcessingFilter,exceptionTranslationFilter,filterInvocationInterceptor
			</value>
		</property>
	</bean>
	<bean id="logoutFilter" class="org.acegisecurity.ui.logout.LogoutFilter">
		<constructor-arg value="/index.jsp"/> 
		<constructor-arg>
			<list>
				<ref bean="rememberMeServices"/>
				<bean class="org.acegisecurity.ui.logout.SecurityContextLogoutHandler"/>
			</list>
		</constructor-arg>
	</bean>
 
	...
	<bean id="rememberMeServices" class="org.acegisecurity.ui.rememberme.TokenBasedRememberMeServices">
		<property name="userDetailsService" ref="userDetailsService"/>
		<property name="key" value="TotoEstUnCon"/>
	</bean>
	...
	<!-- ACEGI STOP -->

Or la classe org.acegisecurity.ui.rememberme.TokenBasedRememberMeServices
implemente bien l'interface org.acegisecurity.ui.logout.LogoutHandler.
Que faut-il préciser à Spring que ce bean implémente bien cette interface ?
[EDIT]
Je suis en mode "autowire"
