Java Server Faces (JSF) 2.0

The advent of Java Server Faces (JSF) 2.0 has made the life of the UI developer very much easier. A simple JSF would have very minimal files namely XHTML files, a Java bean to hold properties and a web.xml file. Usage of ManagedBean annotations has helped to avoid creating and managing faces-config.xml. Bringing about XHTML files rather than JSP files has created a clear separation of logic between the page designer and the Java Developer. A simple hello world JSF project would have the following files -
1. Hello.xhtml - A well formed XHTML file that contains the JSF tags
2. web.xml - The web descriptor specifies the faces servlet and XHTML contexts
3. HelloBean java bean - A simple Java bean with the "ManagedBean" annotation that holds the properties
