This book is written for Java developers familiar with web frameworks. Its main purpose is for Java developers to learn Spring and evaluate it against other frameworks. One of my hopes is to compare Spring to other web frameworks, or at least show how it can be integrated with other frameworks (i.e. Struts, WebWork, maybe even Tapestry down the road). This book will contain a usable sample application that includes Spring code to wire DAOs and Services together. The book does have a bit of a Struts perspective to it as I have been a Struts developer for almost three years and Struts is the most popular web framework today. It is only natural that I use my experience in my writing.
