Adobe Releases AIR Runtime for the Desktop, Opens Flex
2/25/2008
In a move that will let Web developers use their existing skills to build rich Internet applications for the desktop, smart clients and browsers, Adobe Systems Monday released the first version of its widely anticipated AIR cross-operating system runtime, along with updates to its Flex framework for Windows and Mac OS X platforms.
AIR (short for Adobe Integrated Runtime) is a technology that's been a long time coming. Developed at Macromedia, AIR--along with Flex, ColdFusion, and Dreamweaver--was part of Adobe's $3.4 billion acquisition of the developer tools company in 2005.
Available as a public preview or beta since March 2007, AIR (formerly codenamed Apollo) lets developers use familiar Web technologies such as Flash, AJAX, HTML, and Flex to build desktop apps. Other emerging technologies that promise to synchronize data and bring Web-like functionality to the desktop include Google Gears, Mozilla Prism and Sun Microsystems' Java FX. These technologies are open source.
Adobe AIR 1.0 doesn't have any breaking changes from the December 2007 beta. "There are some licensing details," said Adrian Ludwig, Adobe's platform marketing team manager, "but primarily it was performance and stability." AIR is freely available to developers under the Adobe Apollo EULA license. A Linux version is expected later this year.
Several companies demoed RIA applications in conjunction with the AIR 1.0 release, including FedEx, The New York Times Company, NASDAQ, eBay, AOL and Nickelodeon.
Opening Up Web Development
Flex is built on Adobe's Flash technology; it uses a declarative XML called
MXML and ActionScript. Version
3 integrates AIR extensions into the framework, SDK and Flex Builder tooling.
As promised, Adobe open-sourced the Flex framework and SDK today under the Mozilla
license. The Flash player and Flex Builder 3, an Eclipse-based IDE (U.S. $249),
still require commercial licenses.
Adobe has what Ludwig characterized as "a relatively new but committed movement toward open source" and opening up the Flex SDK is expected to increase its usage. "We're thinking that it is going to significantly affect uptake in the Web developer community, which has strong ties to the open source community -- they are very, very tightly aligned," he said.
Adobe also released today the open source Blaze DS back-end tools (remoting and messaging) for Flex applications.
Flex 3 is an incremental release, according to Ludwig. "Almost all Flex 2 code works very easily in Flex 3," he said.
Adobe announced the new dev tools at its Adobe Engage 2008 event for tech bloggers in San Francisco. The products will also be featured at the 360 FLEX conference
