Beginner needs help with basic spring concepts...

Hello,
I get a nullpointerexception upon restart of my web container. I know exactly which object is null (it is a variable of a session scoped object) but I don't know why it is not reinstanciated by the container and injected into the session scoped object.

Here is the code in the session-scoped SuggestionOeuvreView class that raises the npe:

    private Sculpture _suggererSculpture() {
        log.debug("_suggererSculpture");
        log.debug("Etat de la liste: " + this.sculpturesNonVisitees);
        if (!this.sculpturesNonVisitees.isEmpty() && this.sculpturesNonVisitees.peek() != null) {
            Integer idSculptureSuggeree = this.sculpturesNonVisitees.pollFirst();
            this.sculpturesNonVisitees.addLast(idSculptureSuggeree);
            log.debug("jbmService: " + jbmService);
            return jbmService.findByID(idSculptureSuggeree);//the jbmService object is null hence the npe!!
        } else {
            log.error("Probleme dans _suggererSculpture");
            return null;//todo
        }
    }

Here is the code related to that variable instanciation (still in the same class):

private transient JbmService jbmService;

@Autowired
    public SuggestionOeuvreView(JbmService jbmService) {
        log.debug("SuggestionOeuvreView()");
        this.jbmService = jbmService;
        this.sculpturesNonVisitees = recupererSculpturesNonVisitees();
    }

    @Autowired
    public void setJbmService(JbmService jbmService) {
        this.jbmService = jbmService;
    }

Here is the code of the request-scoped AccueilView class that HAS a SuggestionOeuvreView variable.

 @Autowired
    @ScopedProxy
    public void setSuggestionOeuvreView(SuggestionOeuvreView suggestionOeuvreView) {
        log.debug("setSuggestionOeuvreView");
        this.suggestionOeuvreView = suggestionOeuvreView;
    }

FYI I use JSF 1.2, Tomcat 6.0.18, Spring 2.5.5, Spring Java Config, I don't use XML in order to configure Spring.

Can anyone please help?

Thanks in advance,

Julien.
