In this tutorial series, learn how to build multiserving Web applications. The first tutorial in the series explained how to use Wireless Universal Resource File (WURFL) for multiserving. This follow-up tutorial demonstrates how to incorporate multiserving features into Java���Server Faces (JSF) applications. JSF is a Java API to build user interface components. By incorporating multiserving features into JSF, you are able to build JSF tag libraries and applications capable of serving a variety of wireless clients.
