- Set up and configure GWT SDK, GlassFish server, MySQL server, NetBeans, GWT4NB, Ext GWT , iReport plugins for developing the business application in GWT
- Design a database for sales processing system in MySQL, back up and restore the database
- Identify business entities and the relationships and constraints among them
- Handle events such clicking on buttons, typing in text fields, selecting items in a combo box, selecting radios, selecting menus, and selecting toolbar icons
- Manage entities using entity framework through Java Persistence API (JPA)
- Use iReport for any GWT application to get the output of the reports in both HTML and PDF format
- Create Graphical User Interface (GUI) for accepting user input and display information to the user using Ext GWT
- Control communication between the server and client using GWTRPC mechanism
- Create a WAR file for GWT application and deploy it in Glassfish server
This book starts with developing an application from scratch. Right from creating the layout of the home page to home page elements including left and right sidebars, to placing tree like navigational menu, menu bars, tool bars, banners, footers are discussed with examples.
You will see how to create forms using the Ext GWT library widgets and handle different types of events. Then you will move on to see how to design a database for sales processing systems and learn to create the database in MySQL with the help of easy–to-follow recipes.
One of the interesting topics of this book is using JPA in GWT. Using the JPA object in GWT is a challenge. To use them perfectly, a mechanism to convert the JPA object into plain object and vice versa is required. You will see recipes to use entity classes, entity managers, and controller classes in GWT application. You will efficiently create reports with parameters, variables and subreports, and get the report output in both HTML and PDF format using real-world recipes.
You will then learn to configure the GlassFish server to deploy a GWT application with database. Finally, learn how to trace speed and improve perfomance in web applications using tracing techniques.
