JSF 2.1 Spring Session Scope

Question

I have the following confguration in my JSF Spring application:

<bean id="userSessionBean" class="com.vanilla.beans.UserSessionBean" scope="session">
  <aop:scoped-proxy/>
 </bean>

Then I ha have Spring bean

@Service("userService")
public class UserServiceImpl implements UserService,Serializable{

@Autowired
    private UserSessionBean userSessionBean;

public String getCurrentUser(){
  return this.userSessionBean.getUserName;
}
}

Now I have my managed bean:

@ManagedBean(name="userBean") @RequestScoped public class UserBean {

@ManagedProperty(value="#{userService}")
    UserService userService;

   public Sttring getUserName(){
    return userService.getCurrentUser();
   }
}

then I have xhtml

<h:outputText value="#{userBeanBean.userName}" />

All my flow works fine, but when my session expires I'm getting the following error and I'm clicking on refresh I have the following stacktrace:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.userSessionBean': 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: Cannot create a session after the response has been committed

Please add this:

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

To your web.xml

If that will not help please add more info about your web.xml and jsf config.
