I wouldn't say that Open Session In View is considered a bad practice; what gives you that impression?

Open-Session-In-View is a simple approach to handling sessions with Hibernate. Because it's simple, it's sometimes simplistic. If you need fine-grained control over your transactions, such as having multiple transactions in a request, Open-Session-In-View is not always a good approach.

As others have pointed out, there are some trade-offs to OSIV -- you're much more prone to the N+1 problem because you're less likely to realize what transactions you're kicking off. At the same time, it means you don't need to change your service layer to adapt to minor changes in your view.
