BindowsFaces is a components library that enables you to create powerful Ajax web applications with a Windows look-and-feel - using Java through JSF.
Most JSF based frameworks in the market provide the client side components as an afterthought - their client side is quite weak.
BindowsFaces provides Java developers with a market leading client-side component model, built from the ground up with TRUE object-oriented Ajax.
Bindows is famous for being full, rich and mature (probably the richest Ajax framework). Bindows also provides the best in market support for developing Section-508 accessible web applications.
