[GIS] Re-projection in Geoserver

coordinate systemgeoserverwms

I have published a layer on Geoserver by cascading a remote WMS. i have successfully got all the layers from remote wms and publish one of those layers. But I want to re-project the layer from its native srs wgs84 to declared srs EPSG 3011. But when i displayed this layer in my openlayers application, it did not displayed. Then i go back to geoserver and change the declared srs to wgs84 as well, this time the layer displayed successfully.
my question is, why the layer not re-projected ?. OR is there any other way to re-project the layer other than mentioned above?

You shouldn't be using the force SRS box for that - Tell GeoServer what the projection of the layer really is and then let GeoServer handle the reprojection for you when you make the request.

I am aware of the option to set the "declared SRS" when publishing a layer in Geoserver, [...] But is there a way to re-project the coordinates on-the-fly?

That's exactly how you enable on-the-fly reprojection.

Reprojection that's not "on-the-fly" would mean that you have to upload the layer in the correct/final CRS.

Update:

GetFeatureInfo() was not designed to retrieve the vector geometry of objects. It will only return the original data (geometry and attributes). If you need reprojected vector geometries, you'll have to use a WFS.

On the protocol definition, you need to set srsName:

        new OpenLayers.Layer.Vector('Wells', {
            strategies: [new OpenLayers.Strategy.BBOX(), config.saveStrategy],
            protocol: new OpenLayers.Protocol.WFS({
                url: config.vectorWfs,
                featureType: "Wells_PRS",
                featureNS: "http://gisxxxx",
                geometryName: "GEOM",
                srsName: 'EPSG:4326'
            }),
            version: "1.1.0"
        }),

You do not need proj4js.
