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.

Our final chapter has covered key production enterprise deployment concepts. We have compiled our Ext JS 4 application into a single all-classes.js file for production use and added the build version and timestamp to the LogonWindow.js file. We then reduced the size of the Maven-generated task-time-tracker.war file by removing all of the resources that were not required for production deployment. This production WAR file only contains the resources required by the application at runtime and excludes all the Ext JS 4 SDK resources and directories that are not required. We then examined the GlassFish deployment process and deployed the task-time-tracker-1.0.war file via the GlassFish admin console. There is still much more for the you to learn about the GlassFish server, but the entrée has been served!

Our Ext JS and Spring development journey now comes to an end. This book has covered an enormous amount of territory and provided a solid foundation for enterprise application development...
