Senro is a new domain-driven development framework using Wicket.
If you want to prototype webapps in Java, Senro is a great way to go. By annotating a simple POJO data model, Senro will generate a complete webapp in Wicket on the fly. We focus today on Hibernate, but any OR mapper will be supported, eventually.
You probably don't unless you are a developer that is contributing to the project. It's not really ready for people to use yet.
Get on the Senro developer mailing list and get involved. New developers start on a 90-day probationary period. If your code style and quality meet our standards, you'll be welcomed as a full member of the team.
