Hi there!
I want to display the content of a shapefile using mapserver with
openlayers. I did it successfully in cases where the layer's type is POLYGON
but I still don't know where is the problem to do it when the layer's type
is LINE.
Here are informations about my shapefile displayed with ogr info:
INFO: Open of
`C:\ms4w\Apache\htdocs\my_shape_files\shape_ams\EXP_SEGMENT_FONCTIONNEL.shp'
using driver `ESRI Shapefile' successful.
Layer name: EXP_SEGMENT_FONCTIONNEL
Geometry: Line String
Feature Count: 6
Extent: (633527.743437, 2517184.387950) - (669562.958005, 2556945.272294)
Layer SRS WKT:

ID_SEGMENT: Real (24.5)
ID_RESEAU: Real (24.5)
TYPE_ETB_O: String (5.0)
ID_ETB_ORI: Real (24.5)
TYPE_ETB_E: String (5.0)
ID_ETB_EXT: Real (24.5)
CODE_OUVRA: String (30.0)
ID_RAMONAB: Real (24.5)
CLASSIFICA: String (80.0)
LONGUEUR_S: Real (24.5)
PME: Real (24.5)
EXPL_DEGS_: String (80.0)
COMMENTAIR: String (255.0)
PK_INIT: Real (24.5)
ID_ENTITE_: String (30.0)
STATUT_CON: String (1.0)
AUTEUR: String (80.0)
DATE_DERNI: Date (10.0)
Here is the content of my mapfile:
MAP

END
END
END
END
finally here is the content of the html file with the javascript code:
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<title>MapServer Layer: AMS Example</title>
<script src="../../lib/OpenLayers.js"></script>
<script type="text/javascript">
var map, layer, mybounds;
function init(){
map = new OpenLayers.Map("map");
layer = new OpenLayers.Layer.MapServer( "Exemple AMS", "
http://localhost:8081/cgi-bin/mapserv.exe?map=/ms4w/Apache/htdocs/my_examples_MS/ams_exp.map";,
{layers: "EXP_SEGMENT_FONCTIONNEL", format: 'image/png', isBaseLayer: false,
opacity: 1});
map.addLayer(layer);
mybounds = new
OpenLayers.Bounds(633527.743437,2517184.387950,669562.958005,2556945.272294);
map.zoomToExtent(mybounds);
map.addControl( new OpenLayers.Control.LayerSwitcher() );
}
</script>
</head>
<body onload="init()">
<div id="title">MapServer Layer: AMS Example</div>
<div id="map"></div>
</body>
</html>
I tried to display this shapefile without using openlayers and it worked so
I guess the problem is in the javascript code probabily when calling the
method *OpenLayers.Layer.MapServer()* but when I tried to debug the code I
found no errors! Note that I did the same way to display other shapefiles
content having TYPE POLYGON with openlayers using mapserver and that worked
well so I don't know what else to do now!
Please HELP!
