Lightstreamer and SitePen demonstrate "Streaming AJAX" capabilities based on the Dojo Toolkit

Milan, January 17th 2007 – The Dojo Toolkit, a modular open source JavaScript library designed to ease the development of AJAX-based applications, has been integrated with Lightstreamer, a high-performance Streaming-AJAX (Comet) engine. SitePen has developed a Dojo application showing real-time server-pushed data displayed through tables and charts.

Lightstreamer is a push server for live data distribution to "zero-install" clients, based on the Comet paradigm (also known as "Streaming AJAX" or "AJAX Push"). The role of Lightstreamer software is to deliver any real-time data from the server to the browser in a fast and reliable way. Once the data has reached the browser, the Dojo Toolkit is a perfect option to incorporate and use it inside a state-of-the-art AJAX application.

SitePen, a web development & consulting firm based in Silicon Valley, has developed a proof of concept that demonstrates a Dojo application that subscribes to live security prices published by Lightstreamer Server and displays them inside a Dojo table. The recent release of the Dojo Charting Tool has been leveraged to display the live prices in a graphical format as well. Streaming charts based on pure thin clients (with no applets, plug-ins or other external components) are a leading-edge application of the Comet paradigm, that will be especially appreciated by financial institutions.

"This demonstration further emphasizes the possibilities of the real-time web", said Dylan Schiemann, CEO of SitePen, Inc. and co-founder of the Dojo Toolkit. "Dojo's widget system and event model are well-suited for integrating with Lightstreamer’s Comet server. Quite frankly, we were blown away by the ease and simplicity of getting Lightstreamer up and running within just a few minutes."

"The seamless integration between Lightstreamer and Dojo is an important achievement", said Alessandro Alinone, CTO of Lightstreamer. "We are a very focused company and our goal is not to provide a general AJAX framework. Our mission is to deliver a high-performance and reliable push server that can work with any AJAX solution. That’s why Lightstreamer has recently entered the OpenAjax Alliance."

About Lightstreamer:
Lightstreamer is a high-performance push/streaming engine based on the AJAX-Comet paradigm that delivers real-time textual data to Web browsers and to thick applications. When using browsers as a client, nothing is installed or downloaded (no applets or ActiveX, but only pure HTML/JavaScript). Lightstreamer was originally developed by the Financial Systems Integration activity of privately held Par-Tec SpA group (founded in 1998). In 2004 a separate company was formed within the group as an ‘ISV’ to provide Lightstreamer 'Push' middleware solutions for streaming real-time Market Data, or any live information, to web browsers and custom application clients. Lightstreamer is compatible with many browsers on the market, such as Internet Explorer, Firefox, Opera, Netscape, Safari, etc. For more information see where several on-line demonstrations are available.
