HybridJava is a server-side Java Web presentation layer Framework. On one hand it is a minimalistic framework: all documentation is few pages. All the run-time is about 1000 lines (included as Open Source). A separate section of documentation contains a list of things that are NOT used. That includes JavaBeans, XML, and so on an so forth.
On the other hand in some fundamental concepts the technology surpasses many of mainstream frameworks including Struts 2, Wicket, JSF, Spring MVC, Velocity, Razor (C#), PHP and so on. In particular the framework offers a unique MVC component model where not only the pages but also each component is an MVC entity.
