[OpenLayers-Users] unable to create WFS layer from Mapserver

[sunny74]

Dear Friends,

I am trying to create a WFS layer,either singly or on top of a WMS layer but
it gives me an error "htmlfile: Unspecified error".

My code is as below:

var lon = 73.25;
  var lat = 20.35;
 var zoom = 6;
 map = new OpenLayers.Map('<%=map.ClientID%>');

 layer = new OpenLayers.Layer.WMS("OpenLayers WMS",
"/cgi-bin/mapserv.exe?map=c:/ms4w/apache/htdocs/Shape/newwr1rec.map", {
layers: "state", transparent: false, format: "image/png" }, { isBaseLayer:
true });
 map.addLayer(layer);
 layer = new OpenLayers.Layer.WFS("myWFS",
"/cgi-bin/mapserv.exe?map=c:/ms4w/apache/cgi-bin/Shape/wfs_map.map", {
typename: 'state', maxfeatures: 10 }, { featureClass: OpenLayers.Feature.WFS
});
  map.addLayer(layer);
 map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);
 map.addControl(new OpenLayers.Control.LayerSwitcher());

I tried different codes for the WFS but nothing seems to work.I tried the
following
for eg,

var layer1 = new OpenLayers.Layer.Vector("WFS", {
            strategies: [new OpenLayers.Strategy.BBOX()],
            protocol: new OpenLayers.Protocol.WFS({
            url:
"/cgi-bin/mapserv.exe?map=c:/ms4w/apache/cgi-bin/Shape/wfs_map.map",
                featureType: "state",
                featureNS:
"/cgi-bin/mapserv.exe?map=c:/ms4w/apache/cgi-bin/Shape/wfs_map.map"
            })
        });

my wfs map file is as below

    END
  END

  
END

Can some correct the OL/map file code so that I am able to create a WFS
layer successfully.
The template file is a blank file.Is it necessary to have any specific
template.

Thanks for your attention and efforts.
