[OpenLayers-Users] Re : Problem with WFS layer

[Nicolas Caussin]

Hi Jan,

I already try :


var wfs = new OpenLayers.Layer.WFS(
"ArabianGulf",
"http://localhost:8080/cgi-bin/mapserv.exe?MAP=C:/ms4w/wfs/ArabianGulf.map&",
{
typename : "ArabianGulf",
projection: new OpenLayers.Projection("EPSG:900913")
}
);
But there is no difference.

Nicolas.

Hi,

You need to tell OpenLayers again what projection your WFS is in.
So add a projection parameter to your wfs layers

Kind regards,

Jan
