Re. Re: [OpenLayers-Users] Unable to see WFS layer created by GeoServer

[Boyle Robin]

Hi Jorge,

I did the steps you prescribed and - hey presto! - I can see my data.  I can pan and zoom as expected.  Everything looks as it should; however...I still have a JavaScript error:

Error: this.layer.protocol.read is not a function
Source File: http://vmfiddich/openlayers-2.10/OpenLayers.js
Line: 1817

Any ideas?

Thanks for your input!!!

Robin

Hi Robin,

1)

Try to see if this URL works:

http://vmfiddich:8081/geoserver/RobinTest/wfs?service=WFS&version=1.0.0&request=DescribeFeatureType&typeName=RobinTest:datazones_2001 <http://vmfiddich:8081/geoserver/RobinTest/wfs?service=WFS&version=1.0.0&request=DescribeFeatureType&typeName=RobinTest:datazones_2001> 

2)

Get the xmlns:RobinTest location from the result, to put the same location in featureNS

3) Use something like:

var wfs = new OpenLayers.Layer.Vector("Datazones 2001", {

strategies: [new OpenLayers.Strategy.BBOX()],

protocol: new OpenLayers.Protocol.WFS({

version: "1.1.0",

url: "http://vmfiddich:8081/geoserver/wfs <http://vmfiddich:8081/geoserver/wfs> ",

featureType: "datazones_2001",

featureNS: "location from step 2)",

geometryName: "the_geom",

schema: 

"http://vmfiddich:8081/geoserver/RobinTest/wfs?service=WFS&version=1.0.0&request=DescribeFeatureType&typeName=RobinTest:datazones_2001 <http://vmfiddich:8081/geoserver/RobinTest/wfs?service=WFS&version=1.0.0&request=DescribeFeatureType&typeName=RobinTest:datazones_2001> ",

})

});

3.1)

Right now, you don't need to specify a style. OL will use the default style. Later, when it works, put your own style. Keep it simple as possible for now.

4)

In Firebug, check if the request is being done

5)

If not, or just in case, use a local proxy to ensure you are not using different domains, i¨¦ OpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url=";

6)

Check once more the WFS post request and answer in Firebug

Good luck,

Jorge
