Thanks for your help in the first step. You've been right, the problem was
with projection. It's resolved but the WFS features do not show up.
Before you mentioned that it might be a projection problem, I copied the
request string (obtained by getFullRequestString function of WFS class) in
the address bar and I received a GML2 file with some features. However, that
request string doesn't include the BBOX parameter.
I took your advice and fixed the SRS settings on the server and client. When
I copy the request string (obtained from the log file of the Geoserver which
has the BBOX parameter in it) to the address bar, the returned GML2 file
contains only those features which are in the BBOX. Before fixing the
projection problem, this file doesn't have any feature member (an almost
empty GML2 file).
As I mentioned before, I cannot see the features on the screen yet. The SRS
settings on the server for this layer are as follows:
native srs: EPSG:32639
declared srs: EPSG:32639
srs handling: keep native
And my script is the following:
var map, layer, wfs;
function init() {
var bounds = new OpenLayers.Bounds(431834.067, 3887548.528,
684784.466,
4002241.703);
var options = {
maxExtent : bounds,
maxResolution : 859.9516562499998,
projection : "EPSG:32639"
};
map = new OpenLayers.Map('map', options);
layer = new OpenLayers.Layer.WMS("OpenLayers WMS",
"http://localhost:8080/geoserver/wms";, {
layers : 'naji:TBL_GIS_ARC'
});
wfs = new OpenLayers.Layer.WFS("WFS",
"http://localhost:8080/geoserver/wfs";, {
typename : "naji:TBL_GIS_FEATURE_POINT",
maxfeatures : 1000,
format : OpenLayers.Format.GML.v2
});
wfs.isBaseLayer = true;
map.addLayer(layer);
map.addLayer(wfs);
map.addControl(new OpenLayers.Control.LayerSwitcher());
map.zoomToExtent(bounds);
}
Last point: I am using the "full" OL instance and the Geoserver is on the
same machine where the above script is hosted.
I am completely stuck at this point, and would appreciate any help.
Thanks,
Majid
