It looks like some good practical applications of Spring is provided here. Good luck with the book!
I've got few questions on the content:
1. Is the book more concerned about the web tier and the front end of the application (by looking at the Application Recipes part)?
2. What is the "site-up framework" is talking about?
3. I guess Part#3 of the book is being written as a TOC not listed for that? What kind of content it talk about? Is it more theoretical or with sample applications about ?
