Jspx-bay
jspx-bay, commonly referred to as jspx, is a free open source pure Java web RAD framework. Jspx should not be confused with other technologies using the same name like Oracle Application Framework and XML JSP.
Jspx extends Java EE servlets to provide an Object-oriented programming model for HTML declarative code. Jspx can be compared to JSF as a web framework. There are many other Java Web frameworks like Apache Wicket that implement such ideas.
