thanks for the response. I'm not sure I understood it completely :) but I'll use the SpringBean for now.

Re: the preferred way to inject to model objects
You could use Salve (beat you to it, Igor!). Or, you can use AspectJ along with @Configurable/@Autowired. The reason we have to use @SpringBean and not @Configurable in Wicket is that usually the reference to the injected bean is "passed around" to other places. Spring doesn't handle the deserialization of these passed-around beans very well (it only instruments the @Configurable class with AspectJ and they don't inject proxies that are smart enough to deserialize themselves properly). In the case of a domain entity, I would doubt you'd be passing the reference around that much.

the preferred way to inject to model objects
Hi, Usually I inject to object models (Spring) with the Injector Holder facility: @SpringBean private ExtractionManager extractionManager; and in the constructor: InjectorHolder.getInjector().inject(this); I saw in the book WIA (sorry, I don't remember where exactly. Even after looking), that the bean is passed in order to have less memory (pointers) or something like this. So my question is: Suppose I have a POJO class that is the model and I need to use a bean service. Should I inject as above, or should I pass the bean as a parameter form the component (that the bean was injected there).
