is Adobe AIR's openWithDefaultApplication() not available in the AJAX SDK?

The only documentation of Adobe AIR's openWithDefaultApplication() function I can find is a tutorial for it in the Flex SDK. Is Flex required to use this fu开发者_如何学Pythonnction?

Calling it via JavaScript results in:

TypeError: Value undefined does not allow function calls.

The code I'm using:

var poster = air.File.applicationDirectory.resolvePath('posters/CR-1/CR-1.pps');
air.trace(poster); // [object File]
poster.openWithDefaultApplication();

The application file is likely set to.... <application xmlns="http://ns.adobe.com/air/application/1.5">

You must change it to

<application xmlns="http://ns.adobe.com/air/application/2.0">

for the 2.0 + functionality to work....
