Invoking google maps, help plz !

[Vashu]

Hello
First of all forgive me if my english is not perfect! :P

I am developing a blackberry application that works with Google Maps and KML files. I know i can call Google Maps from my aplication and make it load a KML file from a URL, but i would like (if possible) to call Google Maps loading a KML file previously stored, i.e "file:///store/home/user/du.kml"
Does anyone know if this is possible?

Thanks a lot
