Hi
Here is the code I have tried, but I dont know what is the value for the
"featureNS" parameter for the above remote query.
Here is the proxy part of the store
OpenLayers.ProxyHost="/
geoserver/rest/proxy?url=";
proxy: new GeoExt.data.ProtocolProxy({
protocol: new OpenLayers.Protocol.WFS({
url:
"http://SDMDataAccess.nrcs.usda.gov/Spatial/SDMNAD83UTM.wfs<http://sdmdataaccess.nrcs.usda.gov/Spatial/SDMNAD83UTM.wfs>
",
version: "1.1.0",
featureType: "MapunitPoly",
featureNS: "",
srsName: "EPSG:4326",
extractAttributes: true
})
})
This is working with my local geoserver where i know the value of
"featureNS".
I am able to retrieve data successfully with "OpenLayers.loadURL( url
,"","",responsedata)
where url is the full WFS query with filters. Then I could parse the
response data with
OpenLayers.Format.GML.read(response.responseXML)
But here I have no idea how to connect the responsedata to the store ?
Is it possible to pass the whole querey as string in the url part of the
ProtocolProxy ? If it is possible I can apply the filters in the
server-side which may improve the performance.
It would be great if you could help me to figure out this.
Thank you
