You can do it client-side in JavaScript. You can check the source out here.

The geometry object has a method, toJson(), that will do this for you: Javascript API Reference

That method generates an object. It doesn't generate an object that conforms to the GeoJSON spec. – Derek Swingley Mar 19 '12 at 18:26
Yes,toJson() method will return EsriJSON.But I want GeoJSON format. – SureshRajamani Mar 20 '12 at 12:20
