Hi Sowmya,
You're almost there. The last issue you're having (i.e. WMS 1.3.0
returning an empty map) is probably related to the coordinate order in
the BBOX param of your WMS 1.3.0 request.
You're not the first to be hit by this "feature" of WMS 1.3.0. Welcome
to the club! :-)
A more complete explanation is available here:
