[mapserver-users] Open Layers Problem

Arnd,

Thanks for the test and the link showing one of our test map WMS layers. I
good to know it is working now after fixing the map  file path. I have been
trying to get the map image in OpenLayers but cannot yet make it show. As
you, I think that the issue now is that the sample is very small and scale
settings shall be used. This is what I have put together but still cannot
see it

	function init() {
        // Setup our map object
        map = new OpenLayers.Map('map_element', {
        	controls: [
        	new OpenLayers.Control.Navigation()
        	new OpenLayers.Control.PanZoomBar()

        	});

       // Setup our layer objects

    var layer1 = new OpenLayers.Layer.WMS(
		"Caminos",
		"http://173.236.45.118/cgi-bin/mapserv?", 
		{map: '/home/bicimapas/mapdata/BiciMapasMS.map', 
		layers:'caminos'});

    //Add layers to the map
    map.addLayer([layer1]);

        // Add a layer switcher control
    map.addControl(new OpenLayers.Control.LayerSwitcher({}));

   var map_center = new OpenLayers.LonLat(-99.24801,1949775); 
	 if(!map.getCenter()){
			map.setCenter(map_center);
		}
  	}

<body	onload='init();'> mapa de prueba
    <div id='map_element' style='width: 500px; height: 500px;'>

What should be changed?

your server
http://173.236.45.118/cgi-bin/mapserv?map=/home/bicimapas/mapdata/BiciMapasM
S.map
works also well with OpenLayers.

This should show your server with OpenLayers:

http://gis.ibbeck.de/olclient/OLClient.asp?WMC=./data/WMC/BiciMapasMS.wmc.xm

Perhaps you use not the right zoomlevel in OpenLayers to see anything. I
have to use zoomlevel 16 to see something.

by the way also you have corrected it, the mapfile path have to be a
filesystem path and not an url.
