Using ICEFaces with JPA Tutorial
Juan Camilo Ruiz (with a little help from me) wrote a nice how-to that shows you how to integrate the Ajax enabled JSF components offered by the open source ICEFaces project into JDeveloper and how you can work with them and connect them to a JPA/EJB 3.0 back-end.
Check the tutorial out here.
And if you like it and you are at the Oracle Open World Latin America in Brazil - stop by the JDeveloper booth and have a look at all the other things we offer for JSF development (and you might meet Juan there too).
