Enterprise Application Development with Ext JS and Spring

By: Gerald 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.

Chapter 1. Preparing Your Development Environment

This chapter will install and configure your development environment. The Rapid Application Development (RAD) tool is NetBeans, an open source, cross-platform Integrated Development Environment (IDE) that can be used for creating visual desktop, mobile, web, and Service-Oriented Architecture (SOA) applications. NetBeans officially supports Java, PHP, JavaScript, and C/C++ programming languages, but it is best known for providing a complete toolset for all the latest Java Enterprise Edition (Java EE) standards (currently Java EE 7).

The database of choice for this book is MySQL, the world's most widely used open source Relational Database Management System (RDBMS). MySQL is the most popular choice of database for web applications hosted on Linux platforms and continues to deliver outstanding performance in a multitude of applications. Its small footprint and ease of use makes it perfect for development use on a single computer.

The application server used in this book is GlassFish 4, which comes bundled with the NetBeans download. GlassFish is installed as part of the NetBeans installation, and the tight integration between the two makes configuring GlassFish a simple process. GlassFish is an open source, production-quality application server that implements all the Java EE 7 features. It has enterprise-grade reliability and is considered by many to be the best open source application server available. GlassFish 4 is the Reference Implementation (RI) for the Java EE 7 specification, a full description of which can be found at

All of these development tools are freely available for PC, Mac, and Linux. Each tool has extensive examples, comprehensive tutorials, and online support forums available.

It should be noted that although this chapter focuses on NetBeans, MySQL, and GlassFish, it is possible for you to configure any appropriate combination of tools that they are familiar with. The development tasks outlined in this book can just as easily be followed using Eclipse, Oracle, and JBoss—although some described configuration details may require minor modifications.

In this chapter, we will perform the following tasks:

  • Install the MySQL Database server

  • Install the Java SDK

  • Install and configure the NetBeans IDE

  • Create the application project and explore Maven

  • Run the project in GlassFish
