This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
I'll leave this question for Cay, who will be here tomorrow. Cay wrote that chapter.
At a high level, though, the chapter shows you how to use JSF in conjunction with services such as databases, LDAP, web services, etc. There's really not a lot of new information on JSF per se in that chapter, but it's nice to see how you access external services in a JSF application.
