msWMSLoadGetMapParams(): WMS server error.

[Jason M. Amador]

Some javascript/style in this post has been disabled (why?)

Hi,

 

I am trying to make a WMS GetMap request in C# using the OWSRequest object but I am getting the following error.

 

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

<!DOCTYPE ServiceExceptionReport SYSTEM "http://schemas.opengis.net/wms/1.1.1/exception_1_1_1.dtd">

<ServiceExceptionReport version="1.1.1">

<ServiceException code="LayerNotDefined">

msWMSLoadGetMapParams(): WMS server error. Invalid layer(s) given in the LAYERS parameter.

</ServiceException>

</ServiceExceptionReport>

 

I can successfully make WMS GetCapabilities and GetMap requests through the browser directly.  I also have no problem making a WMS GetCapabilities request in C# by using the OWSRequest object.  It’s just when I do a GetMap request that I get the above error.

 

My map file is below.

 

MAP

  NAME            CensusTract

  IMAGETYPE      JPEG

  EXTENT         -125.00 20.00 -65.00 50.00

  SIZE           400 300

  SHAPEPATH       "C:/Inetpub/wwwroot/cgi-bin/ms4w/apps/fhwa/data/CensusTract2005"

  IMAGECOLOR     255 255 255

  CONFIG          "PROJ_LIB" "C:/ms4w/proj/nad/"

  PROJECTION

    "init=epsg:4326"

  END

 

  WEB

    IMAGEPATH "C:/Temp/"

    IMAGEURL "/Temp/"

    METADATA

      "wms_title"       "FHWA Census Tract"

      "wms_onlineresource"    "http://localhost/cgi-bin/mapserv?map=census_tract.map&"

      "wms_srs"               "EPSG:4269 EPSG:4326"

    END

  END

 

  LAYER

    NAME         "censusTracts"

    DATA         CensusTracts

    STATUS       ON

    TYPE         POLYGON

 

    CLASS

      STYLE

        COLOR        232 232 232

        OUTLINECOLOR 32 32 32

      END

    END

    METADATA

      "wms_onlineresource"    "http://localhost/cgi-bin/mapserv?map=census_tract.map&"

        "wms_srs"             "EPSG:4269 EPSG:4326"

        "wms_name"            "censusTracts"

        "wms_server_version"  "1.1.1"

      "wms_title"       "census tract"

      "wms_format"            "image/gif"

    END

    PROJECTION

      "init=epsg:4326"

    END

  END

END

 

 

My C# code is:

-------------------------------------------------

OWSRequest req = new OWSRequest();

 

req.setParameter("SERVICE", "WMS");

req.setParameter("VERSION", "1.1.1");

req.setParameter("REQUEST", "GetMap");

req.setParameter("LAYERS", "censusTracts");

req.setParameter("BBOX", "-125.0,20.0,-65.0,50.0");

req.setParameter("SRS", "EPSG:4326");

req.setParameter("WIDTH", "400");

req.setParameter("HEIGHT", "300");

req.setParameter("FORMAT", "image/gif");

req.setParameter("STYLES", "");

 

mapscript.msIO_installStdoutToBuffer();

 

int owsResult = map.OWSDispatch(req);

-------------------------------------------------

 

Does anybody know what my issue could be or at least point me in the right direction?  I have spent a lot of time researching this already and would really appreciate any help.

 

Thanks,

Jason

Not quite sure of your setup - but can you use something like firebug
in firefox - of maybe fiddler (though you would have to send your call
via its proxy) - to see the actual call being sent to mapserver

I think thats what I'd try as the only thing I can think of is
OWSRequest is mangling the call in some way.  Seeing what its actually
sending might give you a clue ...
