The rise of portable devices last year shows how important is making applications compatible with mobiles. When it comes to web applications, JSF offers the same strong background for mobile development as it does for desktop applications: an extensible framework with a widely-accepted development model, allowing reuse of JSF programming skills and technologies on the mobile platform. RichFaces 4.1 goes behind concepts brought by JSF and provides developer with framework which makes your applications ready for mobile devices and offers you as rich component suite as for desktop environments. Lukas is going to show you how the RichFaces Showcase was turned into an application for portable devices, how a light-weight javascript framework was designed for making RichFaces applications mobile ready, the principles of an one-page application design and what are the necessary optimizations for making RichFaces applications run on mobile devices properly.
