GWT-in-the-AIR is an open source project that makes the Adobe AIR API available for GWT (using JSNI) and provides tools to ease "GWT in Adobe AIR" development:
· a GWT Linker to compile Java to JavaScript and produce an AIR application (or intermediate package) in a single step
· an RMI BrowserManager to run JUnit unit tests within the ADL (AIR Debug Launcher)
· a GWTShell subclass (AIRDebugLauncher) to launch the GWTShell (eventually with the embedded Tomcat) and run the application in the ADL

Given the lack of AIR hosted mode, you would generally use GWT-in-the-AIR when having to develop applications targetting both the desktop and the web.

Requirements:

· Adobe AIR
