This book is perfect for me. I've suffered through heavyweight J2EE projects in years past, worked extensively on Struts servlet-only apps, and spent the last year building a Ruby/Rails application. Now I gotta ramp up for a Spring project and I need a book tailored to getting me started in Spring quickly. This book does that.
The focus is on getting an experienced developer up and running in Spring. I know I can backfill knowledge of Spring internals later with one of those 700 page books. I like that in addition to developing with Spring it ties in most of the nuts and bolts of project development - unit testing, build management, and Spring-specific eclipse IDE navigation.
There's a couple of niggly problems getting set up with maven, a resource location, and a .jpg file, but by simply going to the book's forum on wrox I had that all resolved in less than 15 minutes.
