[OpenLayers-Users] Rich symbolization of vector layers

[Cyril Dejonghe]

Hi list !

I'm new to OpenLayers and I don't manage to display my WFS vector
layer on a OSM base layer.
So what I DO manage to do is :
- my WFS data are correctly set. I use Geoserver to provide WMS / WFS
for cadastral data.
- my js and my WMS server ARE running on the same webapp (as the final
application will be a JEE application, I use TOMCAT for both geoserver
and my app)
- I manage to display a WMS layer with the same data and transparency
- The request generated by OL and the answer of the geoserver seem
correct (some data are transfered, the GML format seems correct)

But if I don't display the WMS layer, I got nothing displayed for the WFS layer.
Last info on my conf :
- my WMS / WFS data are projected in Lambert93.
- i'm using OL 2.11 and GeoServer 2.1.3


So hope you don't mind a snippet of my code...

carto = {
    projs : {
        wgs84: new OpenLayers.Projection("EPSG:4326"), // WGS84
        lambert93: new OpenLayers.Projection("EPSG:2154"),
        spherMercator: new OpenLayers.Projection("EPSG:900913")
    },
    map : undefined,
    layers : {},
    select : undefined,

    init : function() {
        carto.map = new OpenLayers.Map("map", {
            controls: [
                new OpenLayers.Control.Navigation(),
                new OpenLayers.Control.LayerSwitcher( {title: 'Choix
des calques visibles'})],
            projection: carto.projs.spherMercator,
            units: 'm',
            maxResolution: "auto",
            maxExtent: new OpenLayers.Bounds(-3.10, 48.75,-2.99,
48.82).transform(carto.projs.wgs84, carto.projs.spherMercator)
        });

        carto.layers.fond = new OpenLayers.Layer.OSM();

        carto.layers.ilotsWMS = new OpenLayers.Layer.WMS("ilotsWMS",
"http://localhost:8080/geoserver/wms",
            {'layers': 'cultureplus:ilot_2009_022',
'format':'image/png', 'transparent':'true'},
            {'opacity': 0.7, 'isBaseLayer': false, 'visibility': true});

        carto.layers.ilots = new OpenLayers.Layer.Vector("ilots", {
            style : {
                pointRadius: 16,
                strokeColor: "blue",
                strokeWidth: 3,
                cursor: "pointer"
            },
            strategies: [new OpenLayers.Strategy.BBOX()],
            protocol: new OpenLayers.Protocol.WFS({
                version: "1.1.0",
                srsName: "EPSG:2154",
                url: "http://localhost:8080/geoserver/wfs",
                featureType: "ilot_2009_022",
                featureNS: "http://www.openplans.org/topp",
                featurePrefix: "cultureplus",
                visibility : true
            })
        });

        carto.map.addLayer(carto.layers.fond);
        carto.map.addLayer(carto.layers.ilots);
        carto.map.addLayer(carto.layers.ilotsWMS);
        carto.map.setCenter(new OpenLayers.LonLat(-3.05,
48.78).transform(carto.projs.wgs84, carto.projs.spherMercator), 13);
    }
}

Thanks for any help, i'm stuck on this first step...
