[mapserver-users] Re: WMSGetFeatureInfo problem (No results, using OL)

Hi,

Did you try to find the problem first?  You seem to run your own Mapserver.  Then you can see from the Apache access log the requests that your client is actually sending. MS4W installation the log file is by default at ms4w\apache\logs\access.log
Add DEBUG 5 into LAYER definitions in your mapfile. Copy and paste some failing GetFeatureInfo request from access log and resent it with web browser.  See what comes back, and have a look at the Mapserver errorfile which collects the DEBUG data.  It might be better to send GetFeatureInfo requests first against polygon layer because then it is easier to hit a feature by mouse click.  By hand editing the request you will have a full control in what happens.  When you know that the system works with browser you can trust that Mapserver side is OK and you can continue to OpenLayers or other clients.

		Hello guys...

		My mapfile:

		  </head> 

		Template.html
		<!-- MapServer Template -->
		<body> 
		    <b>OID:</b> [oid]
		  </body> 

		Footer.html
		</html>

		WMSGetFeatureInfo  Javascript (OpenLayer)

		var infoCtl = new OpenLayers.Control.WMSGetFeatureInfo({ 
		                    layers: [_test], 
		                    title: 'Click on the map to get information on layers', 
		                    queryVisible: true, 
		                    infoFormat: 'text/html' 
		                }); 

		                infoCtl.events.register("getfeatureinfo",map,showInfo); 

		 function showInfo(evt) {    
		            alert(evt.text);
		} 

		I´m getting that :

		<html> 
		  <head> 
		    <title>MapServer Template Sample</title> 
		  </head> Content-type: application/vnd.ogc.se_xml

		<?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?>

		<ServiceExceptionReport version="1.1.1">
		<ServiceException>
		</ServiceException>
		</ServiceExceptionReport>

		Any idea whats happening?
