Woooh....
So, I have found the problem, but don't kow the reason.
Here is how I make my .bar file:
blackberry-airpackager -package testbb.bar "d:\testbb\testbb-app.xml" "d:\testbb\testbb.swf"
The problem is .bar file doesn't contain .swf file inside, so when I copy it to air folder, it works!
And why it doesn't pack .swf file inside .bar file?
UPDATE: got it working finally, looks like all the files should be within the same directory as blackberry-airpackager.bat file, otherwise it does not pack .swf file.
and this is strange!
