[OpenLayers-Users] Problems displaying kmz file in OpenLayers

[Asle Benoni]

I changed the URL but still get this response:

*OpenLayers.Protocol.WFS is not a constructor
*
 map.addLayer(new OpenLayers.Layer.Vector("Gravminne", {
   strategies: [new OpenLayers.Strategy.BBOX()],
   protocol: new OpenLayers.Protocol.WFS({
       url: "http://naturkart.no:8080/geoserver/wfs&request=getmap",
       typeName: "gravminne",
       featurePrefix: "kulturminner_ns"
   })
   }));
