[flexcoders] SWF download problem

[qau_yasir]

Hello
   I tried to build an application that downloads  a swf file and
installed it. Although the code I used was from the tutorial from
Adobe Livedocs. but still I find exception 
Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never
Completed.

My code is 
private function test():void{   
  try{  
        airSWFLoader = new Loader();         // Used to load the SWF
        loaderContext = new LoaderContext(); // Used to load the SWF 
                                        loaderContext.applicationDomain
=pplicationDomain.currentDomain;
                                        
airSWFLoader.contentLoaderInfo.addEventListener(Event.INIT, onInit);
airSWFLoader.load(new
URLRequest("http://mahmood:8080/C:/Tools/apache-tomcat-5.5.26/webapps/projectClientSerevrDesktop.swf";),
loaderContext);
                                }       
                                catch (e:Error){
                                Alert.show("Error in test() function " +  
e.message,"Error");
                                }                       
                        } 

private function onInit(e:Event):void {

                                 airSWF = e.target.content;
}

Any one know the problem? how to download and run/install .swf file?
regards
Yasir
