Preface

Enterprise application development is an art form rarely acknowledged in this fast-paced technical world. This book describes the patterns and strategies that will simplify large-scale development projects using two of the most popular technologies available: the Spring Framework and Sencha Ext JS. Each chapter defines and builds a concise layer in the enterprise application stack, condensing an approach to web development that was gained from many years of developing real-world projects. We cover quite an extensive conceptual ground, so be prepared for an interesting journey!

This book is not an introduction to Java, JavaScript, or any web development concepts. There are significant amounts of practical code in both Java and JavaScript languages, so an understanding of these technologies is required. If you are not familiar with Java and associated concepts such as object-oriented programming, you may be challenged when following the examples and explanations. The same can be said for Ext JS development; you need to have some experience with the fundamental concepts, including the framework APIs, to follow most examples.

You do not need to be an expert, but beginners may wish to start their journey elsewhere.

Regardless of your experience and background, the practical examples provided in this book are written in a way to thoroughly cover each concept before moving on to the next chapter.
