[Users] WMSGetFeatureInfo-Popup remains empty

[Kai Volland]

Hi,

i have a problem with WMSGetFeatureInfo. I want to show the response 
from the geoserver in a popup-window.
CODE:

/    var featureInfo = new OpenLayers.Control.WMSGetFeatureInfo({
         url: 'http://sfb806srv.uni-koeln.de:8080/geoserver/wms',
         title: 'Info:',
         maxFeatures: 1,
         queryVisible: true,
         eventListeners: {
             getfeatureinfo: function(event){
                 //if( event.text != "\n" && event.text != "") {
                      new GeoExt.Popup({         //utilizing the GeoExt 
popup functionality
                      title: "Info",
                      autoScroll: true,
                      map: map,
                      maximizable: false,
                      collapsible: false,
                      unpinnable: false,
                      anchored: false,
                      location: map.getLonLatFromPixel(event.xy),
                      html: event.text
                      }).show();
                 //}
             }
         }
     });
     map.addControl(featureInfo);
     featureInfo.activate();/

A Popopup shows up, but its empty:

*Response and HTML are empty.*

Some hints refered me to things like proxy.cgi and stuff. But all this 
didn't helped me.

Why do the popup remains empty and how to fix it? Is it because i'm 
runnig it local?

Kind regards

Kai
