Adding KML file in map control by JavaScript API

[AmmarAssem1]

I Have kml file and i need to display it into map control by using javascript api.

In this example http://help.arcgis.com/en/webapi/javascript/arcgis/jssamples/#sample/layers_kml

kml file already published in server when i replace kml url in server by url in my local disk but not work

Locally hosted kml files are not supported. The kml must be available via  a publicly accessible url. See the API reference for the KML layer for details:

I have KML accessible by public IP. but still I am not able to overlay KML on the basemap. "it is giving error spatial reference mismatch. cannot change it at client side."
Then I assigned spatial reference to kml layer as per basemap spatial reference but still not able to overlay.

Plz suggest
