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.

Installing MySQL

MySQL can be downloaded from http://www.mysql.com/downloads/mysql. Select the appropriate MySQL Community server for your operating system and architecture. It is important to follow the instructions, making note of installation directories and paths for future reference. After downloading and running the setup file, you should select the Developer Default installation for this book.

Installing MySQL

Choosing the default settings is best unless you are familiar with MySQL. This will include setting the default port to 3306, enabling TCP/IP networking, and opening the required firewall port for network access (not strictly required for a developer machine where all apps are running on the same environment, but required if you are configuring a dedicated MySQL server).

Regardless of the environment, it is important to set a root user password during the installation process. We will use the root user to connect to the running MySQL server to execute commands.

Installing MySQL

Note

The rest of this book will assume the root user has the password adminadmin. This is not a very secure password but should be easy to remember!

We recommend that the MySQL server is configured to start when the operating system starts. How this is done will depend on your environment, but it is usually performed at the end of the Initial Configuration action. Windows users will have the option to start the MySQL server at system startup. Mac users will need to install the MySQL Startup Item after the server has been installed.

Should you decide not to start MySQL when the operating system starts, you will need to start the MySQL server manually whenever required. How this is done will once again depend on your environment, but you should start your server now to confirm that the installation was successful.

Note

Unix and Linux users will need to install MySQL as appropriate for their operating system. This may include the use of Advanced Packaging Tool (APT) or Yet another Setup Tool (YaST), or even the installation of MySQL from source. There are detailed instructions for various operating systems found at http://dev.mysql.com/doc/refman/5.7/en/installing.html.

At the end of the configuration process, you will have a running MySQL server ready to be used in Chapter 2, The Task Time Tracker Database.
