"And, is there a better alternative than using OpenSessionInViewInterceptor?"
Yes. It's important to realise that while OpenSessionInView feels very handy, it is not a particularly nice design pattern, as it can stress your database with lots of small queries. It's best to learn how to do eager fetching with Hibernate and use it for most cases and rely on OSIV only in some special cases where eager fetching is not possible. This way it's often possible to build entire web applications without resorting to use OSIV.
