Project Apollo seeks to provide a Java based web application development framework. The framework is not a RAD tool, but a set of tools and design patterns which can be used to build a properly designed and robust application.
The Salmon Open Framework for Internet Applications (SOFIA) is a RAD tool set for the J2EE. It integrates best-of-breed tools with a Java framework to provide an end-to-end solution for developing high quality database driven web applications.
