DESCRIPTION

This book is for developers and architects with real Struts work to do. It offers a broad collection of practical solutions complete with detailed code listings that will save you time and money. Each recipe clearly defines the problem it solves, gives you the background you need, and discusses the practical implications of adopting the solution.
