java.lang.IllegalStateException: Cannot deserialize BeanFactory with id org.springframework.web.context.WebApplicationContext

i am using spring 3 with JSF 2, Tomcat 6 and i replaced JSF managed beans with spring beans, by adding on top of bean:

@Component("mybean")
@Scope("session")

and in my bean i am autowiring a spring service (which was declared with the annotation @service)

both spring bean (jsf managed bean/controller) and my spring service implements serializable.

well, everything works fine , but sometimes, i am getting this exception :

java.lang.IllegalStateException: Cannot deserialize BeanFactory with id org.springframework.web.context.WebApplicationContext:/myapp: no factory registered for this id

please advise.

Well, finally i was able to make it work fine as follows:

1- The Service:

@Service
@Scope("singleton")
public class PersonService{

}

2- The Spring Managed Bean:

 @Component("person")
   @Scope("session")
   public class PersonBean implements Serializable{

   @Inject
   private PersonService personService;

   }
