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.

Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, folder names, filenames, file extensions, pathnames, dummy URLs, and user input are shown as follows: "The ManageTaskLogs definition is as follows:"

A block of code is set as follows:

Ext.define('TTT.store.Task', {
    extend: 'Ext.data.Store',
    requires: ['TTT.model.Task'],
    model: 'TTT.model.Task',
    proxy: {
        type: 'ajax',
        url:'task/findAll.json',
        reader: {
            type: 'json',
            root: 'data'
        }
    }    
});

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

controllers: [
  'MainController',
  'UserController',
  'TaskLogController'
],
models: [
  'User',
  'Project',
  'Task',
  'TaskLog'
],
stores: [
  'User',
  'Project',
  'Task',
  'TaskLog'
]

Any command-line input or output is written as follows:

sencha –sdk ext compile -classpath=app page -yui -in index.html -out build/index.html

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Adding a new task log will preserve the currently selected Date and Project, if present:".

Note

Warnings or important notes appear in a box like this.
