Hi Daniel,
Thank you very much. You are a life saver. I was breaking my head all day not understanding what's happening. I just changed the axis order and it worked!!
Thanks again, appreciate all the help.
Sowmya.

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:
