Why i like Spring Roo!

Spring Roo - Next generation java application generator, possible for high quality and productivity of enterprise java applications.

From Roo 1.0 the contributions of Spring Source increased very significantly so that it supported lot of technologies.

The major advantage i found in Spring Roo 1.2.1 is cloud deployment. You can easily deploy your web application into cloud foundry. It is so easy to deploy into cloud - install cloud foundry add -on, logging in into cloud and then upload your web application that's it!.
