Open Source Web Frameworks in Java

The JVx Framework (or JVx - Enterprise Application Framework) is a Full-Stack Application Framework for the Java platform. JVx facilitates the development of professional and efficient Database applications, in a short time and using little source code. The framework's architecture is based on the Multi-tier architecture model for the development of software systems. Building on a three-tier architecture and following the Dependency inversion principle JVx allows for easy development of efficiently maintained applications. The framework provides full support for all tiers. Because of the Single Sourcing principle, the application is coded once and used with different technologies (RIA, HTML/Ajax, Desktop).
