2) Configure proxy server:
OpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url=";
(geoserver work on port 8080)
3) featureNS - it should be the same URL you provided to GeoServer when you created the namespace.
4) check your stylemap object
5) don't use the namespace prefix in the featuretype.

{
url: "/MyApp/Proxy.ashx",
featureType: "boundary",
featurePrefix: "mystore",

})
</pre>
6) use:<br>
<pre id="line91">srsName: "EPSG:3414",</pre>
in Your protocol: new OpenLayers.Protocol.WFS<br>
<pre id="line91">7) try to add: featurePrefix: and schema: parameters to OpenLayers.Protocol.WFS
