cannot display movieclip from swc

[adc_newbie]

i have created a simple program that will display an expression of faces. it was created in flash cs5 and compiled into swc.

i have added the swc in the library path. my problem is i'm not able to display it when i run it in flash builder. here is my code:

package
{
    import flash.display.MovieClip;
    import flash.display.Sprite;
    import flash.utils.getDefinitionByName;
   
    import mood.angry;
   
    mood.angry;
   
    [SWF(width='400', height='500', frameRate='30', backgroundColor='0x000000')]
    public class Faces extends Sprite
    {
        public function Faces()
        {           
            var faceClass:Class = getDefinitionByName("angry") as Class;
            var faceMc:MovieClip = new faceClass() as MovieClip;
           
            this.addChild(faceMc);
        }
    }
}

Explicitly use the class in the SWC.

That is, do:

var faceMc:angry = new angry();
