Hi,
You will be doing exactly same you did in Flex based web
application, when you are developing an AIR application which
communicates with BlazeDS.
Only change i could see is in the Flex based web application,
the tokens in the services-config.xml like {server.root} and
{server.port} are substituted either at run time based on the URL
you use to access the application. Now in AIR application these
might have to be modified to have the hard coded URL to the web
server you are trying to access.
Hope this helps.
