JWt (Java Web Toolkit) is a library for developing accessible and interactive Web applications with an API that is widget-centric and inspired by desktop GUI APIs. To the developer, it offers abstraction of Web-specific implementation details, including graceful degradation. Under the hood, the library uses the latest techniques when available to handle events and update the user interface.
Elefant is a full-featured, but refreshingly simple CMS and PHP Web framework.
