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.

Starting the GlassFish 4 server

Opening the Services tab and expanding the Servers node will list the GlassFish server that was installed during the NetBeans installation process. You can now right-click on the GlassFish Server 4.0 node and select Start as shown in the following screenshot:

The Output panel should now open at the bottom of your NetBeans IDE and display the startup results. Select the GlassFish Server 4.0 tab to view the details.

The fifth-last line identifies that the server has started and is listening to port 8080, written as 8,080 in the log:

INFO: Grizzly Framework 2.3.1 started in: 16ms - bound to [/,080]

You can now open your preferred browser and view the page http://localhost:8080.


Note that depending on your environment, you may have other applications listening to port 8080. In these circumstances, you will need to substitute the correct port, as defined in the GlassFish server output, in place of 8080.

You can now stop the server by right-clicking on the GlassFish Server 4.0 node and clicking on Stop.
