What is Vaadin?

A popular open-source Java framework, Vaadin, is a known name for developing modern and dynamic Java Web Applications. Popularly meant for Rich Internet Applications, it portrays a server-side architecture on which the logic runs. At the browser side, Ajax technology is used to provide an enriching experience to the users. On the client base, Vaadin is constructed and can be extended with the help of the Google Web Toolkit. As seen, Vaadin makes use of Java for the creation of web content.

It uses event-driven programming and widgets, which showcases a programming technique similar to GUI software development. We can deploy Vaadin applications as Java servlets in any Java web server, also in Google App Engine. Vaadin supports integration with the Liferay portal, support for mobile application with Vaadin Touchkit (for iOS5 and above, Android 2.3 and above)


Since Vaadin uses its server and client architecture, it has uniqueness. The client-side manages small rendering and user interactions of the browser, whereas the server-side manages events from the client and changes made to the UI to the client. Between them is the HTTP protocol for communication.

Vaadin’s Development Models

Vaadin Development Model

Vaadin supports the following development models, from which the developer can choose as per requirement:

  • Server Side Java (Swing like)

It is useful for developing applications which are in need of enhanced productivity and for ease of development for the developer.

  • Client-Side Java (GWT)

It is useful for developing applications that need offline support and better support of web browsers. Since GWT is a core part of the Vaadin framework, the user can utilize any component of GWT in the Vaadin framework with ease and least complication.

  • JavaScript

This model is useful to integrate the client part of the application with any other web framework.

Key Highlights of Vaadin

  • No browser plug-in is required since it fully supports HTML5, CSS, and JavaScript.
  • Along with the UI model, data binding with components is available.
  • It provides more than 300 Add-ons which provide good widgets to help develop the application.
  • A simplistic approach as coding is required in Java.
  • Great collection of UI components and robust architecture for Rapid Application Development.
  • It internally handles browser compatibility with developers focussing on coding.
  • Compatibility with major browsers.

We at SPEC INDIA, have developed and successfully implemented rich web applications of one of the topmost medical universities of Switzerland, using Vaadin and GWT architecture.
