[Geoserver-users] Http response error showing KML file

Asle_Benoni · March 26, 2009, 10:57pm

Hello,
I am using GeoServer 1.7.3. I did not see this error in 1.7.2. Or am I doing something wrong?

From FireBug:

The http request:

url
http://borchbio.no:8080/geoserver/wms?bbox=583491.5599999999,6544090.26,666894.4400000001,6637003.74
&styles=&request=GetMap&version=1.1.1&layers=kulturminner_ns:funnsted&width=544&height=550&srs=EPSG:32632
&Format=kml

The response (blank page)

<?xml version="1.0" encoding="UTF-8" standalone="no"?><!DOCTYPE ServiceExceptionReport SYSTEM "http:

//schemas.opengis.net/wms/1.1.1/WMS_exception_1_1_1.dtd">

Could not determine geoserver request from http request org.apache.catalina.connector.RequestFacade
@caa944

Thanks for any help!

Hum, the request is certainly malformed, it's missing the required parameter &service=WMS. Whatever standard WMS request you do the following 3 parameters are required:
- service
- version
- request

Thanks. It does not help adding “service=WMS”. What is strange is that this html works on another server and the request is to the same server.
I have attached screenshots of FireBug when the file is on a remote server (works) and when it is on a local server (doesntwork). I see the header response is different. Can it be something wrong with my Apache? From the server where it works:

Server Apache/2.0.52 (Red Hat)
Connection close

Transfer-Encoding chunked
Content-Type application/vnd.google-earth.kml+xml

The response is different when running the file directly on the server:

Server Apache/2.2.9 (Unix) mod_ssl/2.2.9 OpenSSL/0.9.7l DAV/2 PHP/5.2.6 mod_jk/1.2.23 mod_fastcgi/2.4.2 mod_jk
/1.2.23
MS-Author-Via DAV
Keep-Alive timeout=15, max=499

Connection Keep-Alive
Transfer-Encoding chunkedContent-Type application/vnd.ogc.se_xml;charset=UTF-8

*Server** **Apache/2.0.52 (Red Hat)*
*Connection** **close*
*Transfer-Encoding** **chunked*
*Content-Type** **application/vnd.google-earth.kml+xml*

The response is different when running the file directly on the server:

*Server** **Apache/2.2.9 (Unix) mod_ssl/2.2.9 OpenSSL/0.9.7l DAV/2 PHP/5.2.6 mod_jk/1.2.23 mod_fastcgi/2.4.2 mod_jk*
*/1.2.23*
*MS-Author-Via** **DAV*
*Keep-Alive** **timeout=15, max=499*
*Connection** **Keep-Alive*
*Transfer-Encoding** **chunked*Content-Type** **application/vnd.ogc.se_xml;charset=UTF-8**

Well, yeah, it's different because the second server is reporting
an exception, whose content type is mandated by the WMS spec to:
application/vnd.ogc.se_xml

When you add service=WMS to the request you still get the
same service exception?

Hi,
I am not sure what you mean “running stand alone with mod_proxy to bridge it to Apache”.
I think this must be something to do with Apache. I am running OS X Server 10.5 and could there be something with handlers or mime-types not defined? I thought since it works when the html file is on a linux Apache server. When the html file lies on a server - it is that server that sends the request? My server handles the request if it comes from a linux Apache server but not when the request comes from my OS X Server.

I guess there is an easy way to tell if it’s Apache that is ruining
the request. If you hit GeoServer directly (is it running stand alone
with mod_proxy to bridge it to Apache?) what do you get?

Also, you can change a flag in web.xml to make GeoServer log the
exact request it is seeing. Look for “Request Logging Filter”
and change the enabled param to “true”, then restart GeoServer.

Cheers
Andrea

Hi,
When I run the URL directly on the cgi it returns a CGI file. If I run
it on the CGI on the Linux server it returns a KML file. So definetly
something to do with the way the CGI interprets the request or the way
the request is sent on OS X Server.
