This is a prototype to load external flash9 swf file into flex and using the library items from the swf. In given example we have two library symbols with linkage ids (”mc1″, “mc2″).

Just make sure when you create a movieclip from these definitions, you firstly add these to a UIComponent and then that component to stage or any container, otherwise there will be a conversion error you will be getting

You can download sources from here

Following is the code for the same.
