Thanks for the reply. My map file did have the same configuration as mentioned in the link. The problem is that the data shows up only when i give a particular extent (1610000,6568500,1638000,6594000 in meters) as bbox parameter. So, when i show the entire world on my OL base map, and send a request to fetch this WMS layer, the bbox sent in the request is different and so i get only a blank image. I also tried setting the maxExtent in the WMS parameters as this value but doesn't help.
The extent corresponds to Stockholm. Please help. Thanks a lot.
