Hi,
I am trying to display a map from MapServer in OpenLayer. But it is
displayed only when the zoom level is zero. When the zoom level is some
other level, only a white image is shown.
Can somebody help me with this??
This is my javascript code segment for creating the map.
var map_sv = new OpenLayers.Layer.MapServer( "Clouds",
"http://localhost:7788/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/htdocs/openlayer/map/wms-test.map";,
{layers: "clouds", isBaseLayer: "true"});
This is my map file.
