Spring Roo is a next-generation rapid application development tool for Java developers. With Roo you can easily build full Java applications in minutes. It differs from other productivity tools by focusing on:
MVC applications with JPA are a breeze with Roo, but it also eases your journey into the next generation of technology. We already support cool features like Google Web Toolkit (GWT) for advanced next-generation user interfaces, Solr for search server integration and cloud deployment like Google App Engine. Plus we have incremental database introspection, Flex, Spring Integration and much more actively in development.
SpringSource and Google are working together to combine the speed of development of Spring Roo with the power of the Google Web Toolkit (GWT) to build rich browser apps. Try out the exciting GWT and Google App Engine support now available from Spring Roo 1.1.
