How to import classes form a subdomain

Hi,

I’m having difficulties try to compile a simple Fla file that import classes.

I got 2 directories at same level :
“classes” > that contains all my .as files
“swf” > that contains my fla and compiled swf

Right from a file located in the swf, I have to import a class .as file located in the “classes” folder,

Right now I had “import classes.Slideshow;”
But I get error while compiling, should I write something like :
import …/classes.XMLSlideshow;

Please give me advices.
Thanks!
