> Hello,
>
> I'm trying to get info from a WMS feature, the code I'm using is next:
>
> map.events.register('click', map, function (e) {
> document.getElementById('nodelist').innerHTML =
> "Loading... please wait...";
> var params = {
> REQUEST: "GetFeatureInfo",
> EXCEPTIONS: "application/vnd.ogc.se_xml",
> BBOX: map.getExtent().toBBOX(),
> SERVICE: "WMS",
> VERSION: "1.1.0",
> X: e.xy.x,
> Y: e.xy.y,
> INFO_FORMAT: 'text/html',
> QUERY_LAYERS: 'varetas_2010',
> FEATURE_COUNT: 50,
> Layers: 'varetas_2010',
> Styles: '',
> WIDTH: map.size.w,
> HEIGHT: map.size.h,
> format: format};
> OpenLayers.loadURL("
> http://getcloud.info:8080/geoserver/wms";, params, this, setHTML, setHTML);
> OpenLayers.Event.stop(e);
> });
> }
>
> // sets the HTML provided into the nodelist element
> function setHTML(response){
> alert( response.responseText );
> document.getElementById('nodelist').innerHTML =
> response.responseText;
> };

> And the URL query that server receive from OpenLayers is this one:

> http://getcloud.info:8080/geoserver/wms?REQUEST=GetFeatureInfo&EXCEPTIONS=application%2Fvnd.ogc.se_xml&BBOX=-4.019431%2C37.722122%2C-3.998481%2C37.732959&SERVICE=WMS&VERSION=1.1.0&X=388&Y=124&INFO_FORMAT=text%2Fhtml&QUERY_LAYERS=varetas_2010&FEATURE_COUNT=50&Layers=varetas_2010&Styles=&WIDTH=638&HEIGHT=330&format=image%2Fpng

> My big problem is that I don't know what's happening because the query is

> What could be happening here? Big thanks.
