Before we kick off our look at webapp frameworks, let's establish the domain model we're working with. It's pretty simple - blogs and blog entries, residing in a package called domain.

Because I want to concentrate on the presentation aspects of the frameworks this time around, I'm ignoring the persistence mechanism. Instead, I'm just assuming that data access will be achieved via a "service", regardless of whether it uses direct JDBC, a DAO, a web service, Hibernate, etc.

So that's the model. The question is, will any of the frameworks or view technologies require us to change it?
