Использование Session Scope в Spring Beans

Я использую JSF 2 для представления и Spring для бизнес-логики. Я пытаюсь установить область сеанса для одного из моих компонентов Spring с помощью аннотаций (@Scope ("session")), но получаю следующее исключение:

    SEVERE: Context initialization failed
    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'handleFiles': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private creazione.util.FTPOperations creazione.components.HandleOldFiles.operations; 
nested exception is org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'ftpOperations': Scope 'session' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; 
nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? 
If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

Я знаю о RequestContextListener. Это в моем web.xml. Я также добавил RequestContextFilter:

<listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
    <listener>
        <listener-class>
            org.springframework.web.context.request.RequestContextListener
        </listener-class>
    </listener>

    <filter>
        <filter-name>requestContextFilter</filter-name>
        <filter-class>org.springframework.web.filter.RequestContextFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>requestContextFilter</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>INCLUDE</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>

Похоже, ничего не работает. Что я делаю не так? Спасибо!
