Java Server Faces/JSF 2 Tutorial – Step 1: Project setup, Maven and the first Facelet

Saturday, June 5th, 2010

In this short tutorial we are going to build a Java Server Faces Web-Application using JSF2.0, Facelets, Maven and Hibernate as ORM Mapper.

The goals for this first step are: Setting up the project structure using Maven, defining a frame template/decorator and a registration facelet, creating a managed bean and mapping it’s values to the facelet, adding some basic validation, displaying validation errors and finally adding a navigation structure.

In step2 of this tutorial we are going to add persistence using Hibernate, add some security, create a custom UI component and add some AJAX.

The Mojarra JSF implementation is used for this tutorial – perhaps I’m going to post more about the MyFaces implementation in another tutorial.
