Preface

This book provides an overview of the Vaadin Framework and covers the most important topics that you might encounter while developing applications with it. A more detailed documentation of the individual classes, interfaces, and methods is given in the Vaadin API Reference.

The book has grown greatly after its first edition, until it became too thick to fit any standard pocket. To accommodate all the content also in the printed edition, it has now been split into two volumes, the first one including the topics that you need to get started with Vaadin.

This edition mostly covers Vaadin 7.3 released in 2014. The most notable feature in the release is the new and highly customizable Valo theme.

In addition to the changes in the core framework, this edition features documentation for the TestBench 4 and TouchKit 4 add-ons, which are not yet released at the time of writing. The updated chapters are based on prerelease versions of the add-ons, so the final releases may include some changes.

Writing this manual is an ongoing work and it is rarely completely up-to-date with the quick-evolving product. Some features may not be included in this book yet. For the most current version, please see the on-line edition available at http://vaadin.com/book. You can also find PDF and EPUB versions of the book there. You may find the other versions more easily searchable than the printed book. The index in the book is incomplete and will be expanded later. The web edition also has some additional technical content, such as some example code and additional sections that you may need when actually doing development. The purpose of the slightly abridged print edition is more to be an introductionary textbook to Vaadin, and still fit in your pocket.

Also, many Vaadin 7 features are showcased as mini-tutorials, which are available in the Vaadin Wiki at https://vaadin.com/wiki/-/wiki/Main/Vaadin+7.

Who is This Book For?

This book is intended for software developers who use, or are considering to use, Vaadin to develop web applications.

The book assumes that you have some experience with programming in Java, but if not, it is at least as easy to begin learning Java with Vaadin as with any other UI framework. No knowledge of AJAX is needed as it is well hidden from the developer.

You may have used some desktop-oriented user interface frameworks for Java, such as AWT, Swing, or SWT, or a library such as Qt for C++. Such knowledge is useful for understanding the scope of Vaadin, the event-driven programming model, and other common concepts of UI frameworks, but not necessary.

If you do not have a web graphics designer at hand, knowing the basics of HTML and CSS can help so that you can develop presentation themes for your application. A brief introduction to CSS is provided. Knowledge of Google Web Toolkit (GWT) may be useful if you develop or integrate new client-side components.

Organization of This Book

The Book of Vaadin gives an introduction to what Vaadin is and how you use it to develop web applications.

Volume 1

Chapter 1, Introduction

The chapter gives an introduction to the application architecture supported by Vaadin, the core design ideas behind the framework, and some historical background.

Chapter 2, Getting Started with Vaadin

This chapter gives practical instructions for installing Vaadin and the reference toolchain, including the Vaadin Plugin for Eclipse, how to run and debug the demos, and how to create your own application project in the Eclipse IDE.

Chapter 3, Architecture

This chapter gives an introduction to the architecture of Vaadin and its major technologies, including AJAX, Google Web Toolkit, and event-driven programming.

Chapter 4, Writing a Server-Side Web Application

This chapter gives all the practical knowledge required for creating applications with Vaadin, such as window management, application lifecycle, deployment in a servlet container, and handling events, errors, and resources.

Chapter 5, User Interface Components

This chapter gives the basic usage documentation for all the (non-layout) user interface components in Vaadin and their most significant features. The component sections include examples for using each component, as well as for styling with CSS/Sass.

Chapter 6, Managing Layout

This chapter describes the layout components, which are used for managing the layout of the user interface, just like in any desktop application frameworks.

Volume 2:

Chapter 7, Themes

This chapter gives an introduction to Cascading Style Sheets (CSS) and Sass and explains how you can use them to build custom visual themes for your application.

Chapter 8, Binding Components to Data

This chapter gives an overview of the built-in data model of Vaadin, consisting of properties, items, and containers.

Chapter 9, Vaadin SQLContainer

This chapter gives documentation for the SQLContainer, which allows binding Vaadin components to SQL queries.

Chapter 10, Visual User Interface Design with Eclipse

This chapter gives instructions for using the visual editor for Eclipse, which is included in the Vaadin Plugin for the Eclipse IDE.

Chapter 11, Advanced Web Application Topics

This chapter provides many special topics that are commonly needed in applications, such as opening new browser windows, embedding applications in regular web pages, low-level management of resources, shortcut keys, debugging, etc.

Chapter 12, Portal Integration

This chapter describes the development of Vaadin applications as portlets which you can deploy to any portal supporting Java Portlet API 2.0 (JSR-286). The chapter also describes the special support for Liferay and the Control Panel, IPC, and WSRP add-ons.

Chapter 13, Client-Side Vaadin Development

This chapter gives an introduction to creating and developing client-side applications and widgets, including installation, compilation, and debugging.

Chapter 14, Client-Side Applications

This chapter describes how to develop client-side applications and how to integrate them with a back-end service.

Chapter 15, Client-Side Widgets

This chapter describes the built-in widgets (client-side components) available for client-side development. The built-in widgets include Google Web Toolkit widgets as well as Vaadin widgets.

Chapter 16, Integrating with the Server-Side

This chapter describes how to integrate client-side widgets with their server-side counterparts for the purpose of creating new server-side components. The chapter also covers integrating JavaScript components.

Chapter 17, Using Vaadin Add-ons

This chapter gives instructions for downloading and installing add-on components from the Vaadin Directory.

Chapter 18, Vaadin Charts

This chapter documents the use of the Vaadin Charts add-on component for interactive charting with many diagram types. The add-on includes the Chart and Timeline components.

Chapter 19, Vaadin JPAContainer

This chapter gives documentation of the JPAContainer add-on, which allows binding Vaadin components directly to relational and other databases using Java Persistence API (JPA).

Chapter 20, Mobile Applications with TouchKit

This chapter gives examples and reference documentation for using the Vaadin TouchKit add-on for developing mobile applications.

Chapter 22, Vaadin TestBench

This chapter gives the complete documentation of using the Vaadin TestBench tool for recording and executing user interface regression tests of Vaadin applications.

Supplementary Material

The Vaadin websites offer plenty of material that can help you understand what Vaadin is, what you can do with it, and how you can do it.

Demo Applications

The most important demo application for Vaadin is the Sampler, which demonstrates the use of all basic components and features. You can run it on-line at http://demo.vaadin.com/ or download it as a WAR from the Vaadin download page.

Most of the code examples in this book and many others can be found online at http://demo.vaadin.com/book-examples-vaadin7/book/.

Cheat Sheet

The two-page cheat sheet illustrates the basic relationship hierarchy of the user interface and data binding classes and interfaces. You can download it at http://vaadin.com/book.

Refcard

The six-page DZone Refcard gives an overview to application development with Vaadin. It includes a diagram of the user interface and data binding classes and interfaces. You can find more information about it at https://vaadin.com/refcard.

Address Book Tutorial

The Address Book is a sample application accompanied with a tutorial that gives detailed step-by-step instructions for creating a real-life web application with Vaadin. You can find the tutorial from the product website.
