[GIS] How to set up wfs-t service in Geoserver using openlayers from postgis data

geoserveropenlayers-2postgiswfs-t

I published my postgis data layers into Geoserver.
I have enabled wfs in the edit workspace > services.
Still the "layer preview" does not show any options under wfs. See the image. enter image description here
How can we set up a wfst service using postgis data in Geoserver and see the map in a webpage or qgis?
Does the Geoserver include any example wms/wfs viewers within, (same as the examples folder within the openlayers) so that I can see the wms/wfs/wfs-t with multiple layer overlays? If not how can I add openlayers viewer pages in to Geoserver folder system.

(edited)
Then, where should I put the client files? Sothat I can access from http://localhost:8080/geoserver/ ?
Which directory is the web root within the Geoserver installation?

You cannot have WFS for Grouped Layers.

Grouped Layers are an Geoserver specific service, which works as a Single WMS service containing multiple Layers. This is outside the scope of OGC standards, and it only returns images.

Having a vector group layer for multiple layers does not make sense.

You should be able to access the individual layers as WFS.

I think that your layer is not set up correctly as

var bounds = new OpenLayers.Bounds(
-12.9576148986816, 27.5776710510254,
-0.976616859436035, 36.0192184448242
);
var options = {
controls: [],
maxExtent: bounds,
maxResolution: 0.046800773590803,
projection: "EPSG:900913",
units: 'm'
};

seems wrong - those look like lat/lon values in the bounds object while you have declared the projection of the layer to be Spherical Mercator (900913). This combined with your map making a request for lat/lon data (4326 the default) means that your map is a small dot (probably way smaller than a pixel) near where the meridian crosses the equator.

I think that you would benefit from taking lessons 7 & 8 of my web mapping class.

[GIS] Can’t see WFS-T layer with OpenLayers and GeoServer (Windows)

To expand on my earlier comment for the benefit of Janne and other readers.

When you use OpenLayers to make a WFS (and WFS-T) request you need to be aware of the same-origin policy, this is a clever way to prevent unscrupulous web sites from running malicious javascript exploits on your web browser. Basically what it says is that if a javascript app wants to talk to the network it can only talk to the machine and port combination that it was served from.

This means that if you load a page from http:// localhost:8080 then that is the only place that your script can send requests to. Alternatively if you load your page from file://mytomcat/webapps/mypage.html your script can only send requests to file://mytomcat/... which isn't actually a server so it won't work.
