[Users] How to add WFS and local Vector data ?

[Stefan Schwarzer]

Hmm... searched quite a bit on the net, found a couple of WFS examples (again), and did this to add a WFS layer:



var wfsLayer = new OpenLayers.Layer.Vector("vector", {
	strategies: [new OpenLayers.Strategy.Fixed()],
	protocol: new OpenLayers.Protocol.WFS({
		url: "http://myserver:8080/geoserver/wfs?service=wfs",
		version: "1.1.0",
		featureType: "bafu_ind:mylayer",
		featureNS: "",
		geometryName: "SHAPE", 
		srsName: "EPSG:21781"
	}),
	projection: new OpenLayers.Projection("EPSG:4326")
});

var store = new GeoExt.data.FeatureStore({
    fields: [
        {name: "name", type: "string"}
    ],
    layer: wfsLayer
});



But it's still not working. It's not doing a connection, it seems... Is anything wrong with that code?

Thanks for any hints!
