Transaction handling in 3-tier layered application using Wicket + Spring + Hibernate

Hi,

I'm thinking about using the Open Session In View (OSIV) filter or interceptor that comes with Spring, as it seems like a convenient way for me as a developer. If that's what you recommend, do you recommend using a filter or an interceptor and why?

I'm also wondering how it will mix with HibernateTemplate and if I will loose the ability to mark methods as @Transactional(readOnly = true) etc and thus loose the ability to get some more fine grained transaction control?

Is there some kind of best practice for how to integrate this kind of solution with a three tier architecture using Hibernate and Spring (as I suppose my decision to use Wicket for presentation shouldn't matter much)?

If I use OSIV I will at least never run into lazy loading exceptions, on the other hand my transaction will live longer before being able to commit by being uncommitted in the view as well.
