[mapserver-users] .map file wont display in Open Layers

Mon Jul 13 05:35:00 PDT 2009

Hi, If anyone can help would be greatly appreciated i have been have difficulties displaying my map in Open Layers for little while now.

I have a map file (uk.map) pulling in one layer which is a .shp file consisting of .tiff files i created using FWTools.

However i call the .map file from my html page and the map 

will not display in openlayers just a blank screen within the

Open Layers Window. Can anyone see where i am going wrong?

Here is my map file

And my html page:

<html xmlns="http://www.w3.org/1999/xhtml">
  <head><B><i>NARIMS MAPPING TEST</i></B>
    <style type="text/css">
        #map {
            width: 800px;
            height: 475px;
            border: 1px solid black;
        }
    </style>
    <script src="../lib/OpenLayers.js"></script>
    <script type="text/javascript">

     var lon = 5;
     var lat = 40;
     var zoom = 1;
     var bounds = new OpenLayers.Bounds(-888385.321101, -31000.000000, 1548385.321101, 1271000.000000);      
     var map, layer;

      function init(){
      map = new OpenLayers.Map('map', {maxExtent: bounds});
      map.addControl(new OpenLayers.Control.PanZoomBar());
      map.addControl(new OpenLayers.Control.MouseToolbar());
      map.addControl(new OpenLayers.Control.MousePosition());
      map.addControl(new OpenLayers.Control.OverviewMap());

      layer = new OpenLayers.Layer.MapServer( "OpenLayers WMS",
      "http://127.0.0.1/cgi-bin/mapserv.exe", { layers: 'basic', map: 'c:/ms4w/apps/openlayers-2.5/data/uk.map' }, { gutter: 15 });      
      map.addLayer(layer);
      map.zoomToExtent(bounds);

      map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);      

      }

    </script>
  </head>
  <body onload="init()">
    <div id="map"></div>
  </body>
</html>

Any help much appreciated. Thanks in advance
