Enterprise Application Development with Ext JS and Spring

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.

Introducing Maven

Apache Maven is a tool that is used for building and managing Java-based projects. It is an open source project hosted at and comes bundled with the NetBeans IDE. Maven simplifies many steps common to all Java development projects and provides numerous features, including the following:

  • The provision of convention over configuration. Maven comes with a series of predefined targets for performing certain well-defined tasks including compilation, testing, and packaging of projects. All tasks are managed through a single configuration file: pom.xml.

  • A consistent coding structure and project framework. Each Maven project has the same directory structure and location for source files, test files, build files, and project resources. This common structure brings us easily up to speed with projects.

  • A consistent build system with numerous plugins to make common tasks easy.

  • The ability to execute tests as part of the build process.

  • A highly flexible and powerful dependency management system. This allows software developers to publish information and share Java libraries through (external or remote) Maven repositories hosted on the Internet. Libraries are then downloaded and cached locally by Maven for use in the project.

We encourage you to visit the Maven website to explore the many features available. NetBeans will use Maven to create and manage the web application project.
