google maps - openlayer select wms layer -


in application have googlemap , wms layers coming geoserver, need select features on these layers, followed example: http://openlayers.org/dev/examples/getfeature-wfs.html, no errors, when click on feature, mouse start spin, no result @ all, code:

var ghyb = new openlayers.layer.google(         "google hybrid",         {"type": google.maps.maptypeid.hybrid, numzoomlevels: 20}     );             var options = {             controls: [],             //sphericalmercator:true,             //projection: new openlayers.projection('epsg:900913'), // senza la proiezione mi stampa metà layer             units: "m",             numzoomlevels: 22,                         maxresolution: 156543.0339,             maxextent: new openlayers.bounds(-20037508.34, -20037508.34,                          20037508.34, 20037508.34)             };             var panzoom = new openlayers.control.panzoom();         var map = new openlayers.map('map', {                 div: "gmap",                 projection: "epsg:900913",                 displayprojection: "epsg:4326",                 //zoomoffset: 5         controls: [             panzoom,             new openlayers.control.navigation()         ]         }); var regioni      = new openlayers.layer.wms(             "regioni",             "http://localhost:8080/geoserver/wms",             {             layers: "metmi-italy:reg2011_g" ,             transparent: "true",             format: "image/png",             srs:'epsg:900913', // old: 'epsg:2077'             //zoomoffset: 4,             },             {isbaselayer: false,}         ); control = new openlayers.control.getfeature({         protocol: openlayers.protocol.wfs.fromwmslayer(regioni),         box: true,         hover: true,         multiplekey: "shiftkey",         togglekey: "ctrlkey"         }); select = new openlayers.layer.vector("selezioni", {stylemap:          new openlayers.style(openlayers.feature.vector.style["select"])         }); map.addlayers([ghyb,regioni,select]) control.events.register("featureunselected", this, function(e) {             removefeaturesfromgrid(e.feature.fid);         select.removefeatures([e.feature]);          }); control.events.register("featureselected", this, function(e) {                 console.log('selected')                 select.addfeatures([e.feature]);                 //addfeaturestogrid(e.feature);                  }); map.addcontrol(control); control.activate()

i think there missing, not find it

i have not used getfeature class, use wmsgetfeatureinfo in case.

    var clickcontrol = new openlayers.control.wmsgetfeatureinfo({             url: 'http://localhost:8080/geoserver/wms',             title: 'some title',             layers: [regioni],             queryvisible: true,             infoformat: 'application/vnd.ogc.gml',             maxfeatures: 10     });

as general steps debug, encourage use tools figure out what, if any, http request being made browser. if using chrome or safari, can right click, "inspect element", go network tab, , click map. request should show in network tab , can diagnose if request looks correct , if response looks correct.
