I'm trying to add a WFS layer and it's not working.

WMS layer in this map works perfect, but WFS layer is problem. I put the HTML to GeoServer folder at: C:\Program Files\GeoServer 2.2.5\data_dir\www\complex

and open: localhost:8080/GeoServer%202.2.5/data_dir/www/complex/complex.html, panel and map works, but WFS layer not. Why? Where is the problem?

vgv2 workspace layer "cjevovodi" enter image description here enter image description here

I tried to change projection to epsg:900913, nothing.

  • IMHO, this is far too much code. You will have better chances of getting good answers by isolating the problem to the point where you can illustrate it with less than one page of code. As it stands, you're just asking us to debug this mess, and that's not an acceptable kind of question anywhere on SE. – whuber Jun 14 '13 at 12:50

Firstly try putting you code (JS/HTML) C:\Program Files\GeoServer 2.2.5\webapps\complex folder, and try to access it as http://localhost:8080/complex/complex.html See if you get any error messages in Firebug.

Now coming to your code. Firstly I do not see the projection being set to webmercator. You need to do that.

And finally, I would initialize the WFS service like this:

//wfs layer
var wfsLayer = new OpenLayers.Layer.Vector("cjevovodi", { 
                        strategies: [new OpenLayers.Strategy.BBOX()], 
                        protocol: new OpenLayers.Protocol.WFS({ 
                            url: "http://localhost:8080/geoserver/wfs", 
                            featureType: "cjevovodi", 
                            featurePrefix: "vgv2", 
                            srsName: "EPSG:4326", 
                        }), 
                        isBaseLayer: false 
                    }); 

Further more, there are many questions already on the site about wfs issues. have you gone through all of them?

  • See this answer for example: gis.stackexchange.com/a/57655/442 – Devdatta Tengshe Jun 12 '13 at 9:18
  • Tensgshe Thanks for answer but it´s not work! My layers "cjevovodi" use epsg: 31275, is that problem? Are you sure for C:\Program Files\GeoServer 2.2.5\webapps\complex location? If I try to acess it, I get http 404 error. All I want is shown layer as vector and configure popup window to show attributes. What is better to use, wms or wfs? If I use wfs, I could only view table, but not edit it? Correct? Openlayers load the layer and it shown in layer switcher, but its not on the map. Somewhere is problem, maybe in "proxy.cgi?url="? If I switch that layer to wms it works. – brunci Jun 13 '13 at 9:16
  • If your earlier location was working, then you can continue using it. EPSG 31275 will be a problem, since OpenLayers cannot natively project from it to EPSG:3857. You will need Proj4js to project to use this projection. And since you are on the same port as Geoserver, you will not require a proxy. – Devdatta Tengshe Jun 13 '13 at 10:18
