Enterprise Application Development with Ext JS and Spring

By: Gierer

Overview of this book

Spring and Ext JS are cutting edge frameworks that allow us to build high performance web applications for modern devices, that are now consuming data at a faster rate than ever before. It is the appropriate time for you to understand how to best leverage these technologies when architecting, designing, and developing large scale web development projects. This practical guide condenses an approach to web development that was gained from real world projects, and outlines a simple, practical approach to developing high performance, and enterprise grade web applications. Starting with configuring Java, NetBeans, and MySQL to prepare your development environment, you will then learn how to connect your NetBeans IDE to the MySQL database server. We will then explore the Task Time Tracker (3T) project database structure and populate these tables with test data. Following on from this, we will examine core JPA concepts after reverse engineering the domain layer with NetBeans. Leveraging the Data Access Object design pattern, you will learn how to build the Java DAO implementation layer assisted by generics in base classes, followed by a Data Transfer Object enabled service layer to encapsulate the business logic of your 3T application. The final chapters that focus on Java explore how to implement the request handling layer using Spring annotated controllers, and deploy the 3T application to the GlassFish server. We will then configure the Ext JS 4 development environment and introduce key Ext JS 4 concepts, including MVC and practical design conventions. Covering a variety of important Ext JS 4 strategies and concepts, you will be fully-equipped to implement a variety of different user interfaces using the Ext JS MVC design pattern. Your journey ends by exploring the production build and deployment process using Maven, Sencha Cmd and GlassFish.

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.
