Hi Suvajit,
first off, a couple of directions about making questions on
the mailing lists:
- you have to subscribe to a mailing list before posting a
   question
- the devel list is for meant for developers to discuss the
   technical details and direction of GeoServer, not for users
   making questions about GeoServer features or issues

Ah, I see. EPSG:4900 is a 3D spatial reference system, GeoServer
can only handle 2D data at the moment. So no, EPSG:4900 is not
supported.
