Lightstreamer, the streaming engine for AJAX applications, can now deliver real-time data to Flex applications. Milan, Italy, September 3, 2007 – Lightstreamer is a technology for delivering real-time text data to any clients through the Web. Its server component implements a messaging system based on Http that can manage thousands of streaming connections, where data is pushed to the clients in real asynchronous fashion. Adobe® Flex™ is a cross-platform development framework for creating rich Internet applications (RIAs). A new software development kit (SDK) was released to develop Lightstreamer clients based on Flex and Flash technologies. Now Lightstreamer is a perfect fit for all Flex applications that need asynchronous notifications and messages based on a reliable, optimized and scalable protocol (for example, finance market data, online betting, auctions). “Lightstreamer, since its inception seven years ago, has supported many types of client technologies”, said Alessandro Alinone, CTO of Lightstreamer, “We started with Web clients, based on HTML and JavaScript, well before the AJAX and Comet terms were coined. Then we added more client SDKs, such as Java and .NET. The new Flex SDK was requested by several of our customers, to leverage Lightstreamer Server for both AJAX and Flash/Flex applications, and we are now glad to publicly release it”. The new Flex SDK features a native ActionScript 3 library that handles the communication with Lightstreamer Server and offers a high-level API, used by Flex developers to exploit the publish/subscribe paradigm implemented by Lightstreamer. The Flex SDK, that is shipped as part of Lightstreamer Presto and Vivace editions, will be demonstrated at AjaxWorld 2007 West (September 23-26, 2007, Santa Clara Convention Center, CA). About Lightstreamer Lightstreamer is a push/streaming engine based on the AJAX and Comet paradigms that can deliver real-time text data to Web browsers (pure HTML applications, with no downloads) and to any client applications. The Lightstreamer Server can handle thousands of concurrent clients and implements advanced algorithms, as bandwidths management, congestion control, dynamic filtering. Lightstreamer (legal entity Weswit Srl) is part of Par-Tec Spa. Development began in 2000, originally by the financial system Integration activity within the group, then in 2004 Lightstreamer became an independent ISV to provide ‘push technology’ to a wider global market.
