Seems like Rails has got an answer from the Java community in Trails. I havn’t played around with Rails yet, but I skimmed a couple of tutorials on it. To me it seems Trails is even simpler.
What will be the interesting part about it is how to extend and override default behaviour. If that is flexible enough, it might be a good startingpoint for new projects. If not it will probably start you off on a very DB centric path, and that won’t really be Domain Driven Design will it? (Yeah, I’m a big fan of DDD)
