Hi Pierre,

Thanks for your reply. Your suggestions were duly noted and the
required changes were made. However, the problem still persists in
case of WMS.

1. In case of Layer.WMS:
    I have some queries regarding the projection of the map(which i
believe is epsg:4326):
     Is it necessary to define PROJECTION property within each LAYER
explicitly, even if the same has been defined in METADATA in the WEB
section of the mapfile

2. In case of Layer.MapServer :
     Base Layer is visible but as soon as any of the overlays are
activated, the overlays completely overlap the base layer thereby
making the base not visible.


 The truth of the matter is that these mapfiles are examples from Bill
Kropla's book and have been written for mapserver. I just wanted to
modify them and try using openlayers with the same.

Attached are the modified files
 I shall be grateful if you could provide a pointer or two in this regard.

Thanks
Subhajeet
