eXo Platform comes with a set of advanced portlets to build rich applications quickly. But you may want to develop your own portlets to fit your needs. The development of a portlet using the raw portlet API can be a bit painful; it is often preferable to use a higher-level framework such as JSF. JSF is a request-driven MVC web framework based on a component-driven UI design model, and is part of the JEE standard. This article is the first of a set of three tutorials that will teach you how to develop a portlet with JSF 2.0 and RichFaces 4, and leverage eXo Platform content and social capabilities.
