Hello Everyone,

 

I'm trying to show a layer from an UMN Mapserver onto

my OpenLayers html page. The image from the mapfile is displayed very well

if i request '/cgi-bin/mapserv?map=/srv/www/htdocs/landkreise.map' this url.

 

But if i wan't to show this layer via Openlayers there is a white image.

I think there is something fundamentally wrong I'm doing.

 

Below is the code for both the mapfile and the html page. Please help me

out.

 

Script -Tag in the HTML:

<script defer="defer" type="text/javascript">

 

var proj4326  = new OpenLayers.Projection('EPSG:4326');

var projmerc  = new OpenLayers.Projection('EPSG:900913');

 

            var options = {

    numZoomLevels: 19,

    projection: proj4326,

    displayProjection: proj4326,

                        controls:[
