Grails is a full stack framework for developing Web applications on the Java platform. It builds on the concepts introduced by frameworkds like Rails, Django, and TurboGears, but builds on established Java technologies like Spring and Hibernate. It includes an easy-to-use object relational mapping (ORM) layer, an expressive view technology, a controller layer, a command line scripting environment, an embedded Jetty container which is configured for on-the-fly reloading, dependency injection, support for internationalization (i18n), and a transactional service layer.
Simple and powerful UML editor. Stopped on it after using Umbrello and ArgoUML
Very good project with a lot of useful features out of the box. It icontains the features required to perform PM activities - gather info (wiki), plan, issue tracking (tickets), documents, etc.
