Is your shapefile in the original coordinate system (Dt73_HG)?
If so you must define it in the map parameters (OpenLayers) because the default
is WGS84. Try this:
map = new OpenLayers.Map( 'map',{projection:'EPSG:27492',
units: 'meters',
maxExtent: new OpenLayers.Bounds(-100000, -200000, 200000, 300000),
maxResolution: 'auto'} );
Also, adjust maxExtent to your taste.
You can also define the coordinate system correctly in your mapfile
(MapServer). This way MapServer will be able to reproject your shapefile on the
fly. For this to work replace the shapefile projection with 'init=epsg:27492':
LAYER
NAME 'Cont_Freg_CAOP2008_HG73'
TYPE POLYGON
DATA 'C:\ms4w\apps\wmssrvrefer\data\Cont_Freg_CAOP2008_HG73.shp'
METADATA
'wms_title' 'Cont_Freg_CAOP2008_HG73'
END
STATUS DEFAULT
TRANSPARENCY 36
PROJECTION
'init=epsg:27492'
END
Another problem I spotted in your mapfile is that wms_onlineresource tag is
pointing to a non-existing server. You should point this to your MapServer
otherwise you'll get into trouble when using other wms clients like gvSIG,
QGIS, ArcMap, AutoCAD Map, etc.

Hi,
i?m haviing trouble to show a simple shapefile frmo a wms server
(mapserver).
Here is the mapfile
http://www.nabble.com/file/p18867858/test.map test.map
if i make shp2img -m test.map -o test.png -all_debug 10 the image is made,
so it?s not from mapserver.
the openlayers code is:
map = new OpenLayers.Map( 'map' );
var layer = new OpenLayers.Layer.WMS( "SHAPEFILE",
"http://172.18.210.67:8080/cgi-bin/mapserv.exe?map=/ms4w/apps/wmssrvrefer/test.map&service=WMS";,
{'layers': 'Cont_Freg_CAOP2008_HG73' , 'format':'image/png'});
map.addLayer(layer);
the image shows only the background.
what?s wrong ?
Thanks.
