Ajax, a set of development techniques standardized over the past eight years, could change all that by bringing more sophisticated interfaces to Web applications. Ajax is not a technology in itself, but a term that refers to the use of a group of technologies.

Asynchronous JavaScript and XML (AJAX), is a web development methodology used to create a new generation of interactive web applications. The intent is to make web pages react more responsively by exchanging only small amounts of data with the server, thereby avoiding entire web page reloads each time the user requests a change. This approach is designed to increase the interactivity, speed, and usability of web pages.

For many years, web applications were either static (i.e. implemented using non-interactive plain HTML pages) or dynamic (using JavaScript). While the dynamic nature provided for increased user-interactivity, the developers lacked a standard framework for building their applications and too often had to account for various browserspecific incompatibilities resulting in code that was difficult to maintain.

Moreover, due to the inherent nature of HTTP, every user interaction with a web page generated a complete roundtrip cycle between the client and the server causing a full page refresh. While the client and server were busy communicating, the user’s interaction was essentially suspended.

Ajax is currently applied by developers for creating agile web applications and is growing in popularity among the new breed of so-called Web 2.0 companies. Ajax also allows more traditional IT organizations to update or enhance their existing web applications. To enable rapid Ajax application development, the Web 2.0 community has developed a number of frameworks such as DOJO, JSON (JavaScipt Object Notation), and DWR (Direct Web Remoting).

The Java community also has embraced this trend by creating frameworks to enable the development of Ajax applications in the Java Enterprise Edition (JEE) platform. The frameworks A4J (Ajax for JSF) and JWL (JSF Widget Library) essentially incorporate Ajax-enabled page generation from the Java Server Faces (JSF) components. And Google, who many credit with popularizing Ajax via Google Maps and Gmail, has also released an Ajax development toolkit called Google Widget Toolkit (GWT).

Faiz Arni, president, InferData's said "Ajax creates the required initial conditions for the evolution of complex, intuitive, dynamic, data-centric user interfaces in web pages rivaling the richness and functionality of traditional desktop applications."

He added, "Our courses are primarily targeted at software architects and developers. Our new 3-day Ajax course will cover the techniques, frameworks such as DOJO, and tools that help build professional Ajax-based Web applications. Based on user demand, we also successfully deployed a 2-day Server-side Ajax course focusing on server-side Ajax frameworks such as JSON, DWR, JWL, A4J, GWT and others. We use a highly hands-on approach, with programming labs constituting about 70 percent of the course content."
