Ninja web framework [1] is also worth a look. It's similar to Dropwizard in that it's less of a framework and more like a well thought out archetype building upon the best Java libraries. Two main differences I see are Ninja uses Guice for DI whereas dropwizard is manual DI. Dropwizard uses JAX-RS while Ninja has its own Play 1 style routing system.

While I really like JAX-RS, the reference impl Jersey uses HK2 for dependency injection, which makes it odd to integrate into a Guice application (in fact Guice support is still lacking with Jersey 2.x).
