[OpenLayers-Users] Re: How it works WMSGetFeatureInfo??

Fri Feb 10 07:35:45 EST 2012

With the getfeatureinfo-controls version, I get the map with the layer but
when I click to get info nothing happens.

Firebugs don't get any error and show the request. And if I open it have
the layer info that I want to display beside the map.

http://localhost:8080/geoserver/Proj_CAT/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&LAYERS=Proj_CAT%3AProjectes_UTM31&QUERY_LAYERS=Proj_CAT%3AProjectes_UTM31&STYLES=&BBOX=-3.174805%2C38.253418%2C5.174805%2C43.746582&FEATURE_COUNT=10&HEIGHT=500&WIDTH=760&FORMAT=image%2Fpng&INFO_FORMAT=text%2Fhtml&SRS=EPSG%3A4326&X=455&Y=150

I also have this version in the /www/ folder with the openlayers.js online
<script src="http://www.openlayers.org/api/OpenLayers.js"></script>

If I try to use the downloaded version at www/openlayers/lib/openlayers.js
also says that OpenLayers is not defined

The whole code is this:
