[OpenLayers-Users] Custom Map Service

[Kalyan Kamepalli]

Hi,

I managed to write a custom class that sends the native map requests to my
server.But, the problem is, the response I get from my server is in XML
format and I wanted to show the actual image files on the map. Could some
one tell me where to get handle of  map service reposne please ? so that I
can parse XML response and display images.

You can find the XML reponse down this mail .

Thanks,
Kalyan
