I want to create some squared features with OpenLayers 4, add attributes to each feature and want to save them on the GeoServer to load them later on to another map. I am able to create the features, add attributes to them, read the attributes again and load a layers as WFS again.
My only problem is to save the created features to the GeoServer. I figured out that saving and loading should be possible with WFS-t. I found some examples online but they don't seem to work properly.
When i send the feature to the GeoServer with the function transactWFS at line 133 I get the Error
"org.geoserver.wfs.WFSTransactionException: Feature type 'Stairways' is not available" in the GeoServer log file. The Layer Stairways exists on the GeoServer.
This is the XML file that is sent:

This is my whole Code:
GridSource.addFeature(NewSquare);
var attr = {};
var key = "TestAttr";
attr[key] = "This is a Test";
NewSquare.attributes = attr;
transactWFS('insert', NewSquare);
}
var formatWFS = new ol.format.WFS();
var formatGML = new ol.format.GML({
featureNS: gs.wfs,
featurePrefix: 'HTW_Erd',
featureType: 'Stairways',
srsName: 'EPSG:3857'
});
var xs = new XMLSerializer();
var transactWFS = function (mode, f) {
var node;
switch (mode) {
case 'insert':
node = formatWFS.writeTransaction([f], null, null, formatGML);
break;
case 'update':
node = formatWFS.writeTransaction(null, [f], null, formatGML);
break;
case 'delete':
node = formatWFS.writeTransaction(null, null, [f], formatGML);
break;
}
var payload = xs.serializeToString(node);
$.ajax(gs.ows, {
service: 'WFS',
type: 'POST',
dataType: 'xml',
processData: false,
contentType: 'text/xml',
data: payload,
error: function(e) {
var errorMsg = e? (e.status + ' ' + e.statusText) : "";
alert('Error saving this feature to GeoServer. \n\n'
+ errorMsg);
}
}).done();
};
Edit:
I saw in the log file that i wasnt allowed to write on that layer so i set the permissions. I also changed the projection of the GridLayer to 3857 and the name of the feature to geometry. But that didn't help either. I now don't get any errors and the log looks like this:

All the features that are already in the Layer named 'the_geom', renaming the feature to the_geom doesn't help.
Edit 2:
This is the Output

<ows:Exception exceptionCode="InvalidParameterValue" locator="service">
<ows:ExceptionText>No service: ( wfs\ )</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>
I have to add that I dont have the default layers anymore, so i dont have the topp workgroup and the layer states anymore.

Best Answer
You are telling GeoServer that the namespace for your feature is
xmlns="http://localhost:8080/geoserver/wfs"(orgs.wfs) when it should be the URI associated with your workspace that contains theStairwaysfeaturetype.I would also check to be sure that the layer name really starts with a capital S as it is case sensitive.
EDIT
You will need to set the geometry field name using
in your GML format.
