JavaScript Powers Up the Server Side

Thu, 04 Sep 2008 15:43:00 EDT

Aptana Jaxer is a new open source application server built especially for AJAX application development in JavaScript. To say that "Jaxer lets you do JavaScript on the server-side" would be accurate, but an understatement. The core concept of Jaxer is that it provides a parity of environments at the client and the server to simplify the creation of rich AJAX pages, apps, and gadgets – and by so doing, gives the Web developer a unified runtime at both the client and server tiers.

A Simple Streaming AJAX App with OpenAjax Hub, TIBCO GI, and DWR 2.0

Thu, 26 Jul 2007 10:30:00 EDT

Follow along and implement the real-time streaming AJAX system in Figure 1 using two different AJAX toolkits and the OpenAjax Hub. We don't have to build the above system from scratch, and can instead leverage readily available, reusable AJAX parts to get the job done quickly; the architectural strategy is to use AJAX pieces and parts that can work together. At the core of the system in Figure 2 is the OpenAjax Hub (see the OpenAjax Hub for Interop sidebar). We'll use the OAA Hub as a central publish/subscribe bus to which we can publish the live stock data so that the data grid and the future visual controls and functions can listen for those events and messages.

Real-World AJAX Book Preview: Use of Dummy Data in These Exercises

Fri, 18 May 2007 14:00:00 EDT

Except for the two GUI components that we'll be configuring in this tutorial, the GUI components have been bound to dummy data sets - a technique useful in mocking up GUIs during GUI design processes.

Corporate Mashups: Composite Applications Simplified Through AJAX and SOA

Thu, 17 May 2007 17:45:00 EDT

In this chapter we'll look at rapidly implementing an AJAX Rich Internet Application that leverages various XML and SOAP Web Services while using the visual tools and application objects from TIBCO Software's AJAX toolkit: TIBCO General Interface.

The Big Shift with AJAX and Web Service Bus Architectures

Wed, 16 May 2007 14:30:00 EDT

There have been numerous articles over the last year on how the complementary nature of AJAX and service-orientation together are rapidly transforming the way in which we design, architect, deploy, and manage applications. The ramifications of this change impact nearly every aspect of business application development, from design conception, architectural planning, and implementation to unit testing and monitoring. New methodologies, tools, and infrastructure are now emerging as the industry evolves from the three-tier system concepts that have dominated the last decade on the Web into the Service Oriented Architectures (SOA) currently being implemented.

The Four "Quantum States" of AJAX

Wed, 20 Sep 2006 13:15:00 EDT

Tightly defined, AJAX simply describes a technology that transports information to and from the browser and not how that information is displayed. To purists, AJAX is about communicating asynchronously from the browser using JavaScript and XML, nothing more. To others, through their experiences with Google Maps and Yahoo!'s new e-mail offering, AJAX represents a desktop-like GUI that leverages the pre-existing HTML, DHTML, and vector-based rendering capabilities of the browser. Either way, 'AJAX' is a lot catchier than 'DHVAJAX.' Accordingly, it's likely that developers will continue to use it for a broad spectrum of uses. So, it's important to understand the 'quantum states' the term has taken on.

From Enriched HTML to Client/SOA: The Four Quantum States of AJAX

Tue, 06 Jun 2006 09:45:00 EDT

Today there is a spectrum of architectural approaches to AJAX solutions. At the simple end of the spectrum, HTML pages are becoming enriched with simple AJAX behaviors exemplified by the likes of Yahoo! Maps, Google Suggest and a myriad of AJAX libraries and widgets that have now been published.
