Sorry for replying to my own post, but I am making some progress only to find additional problems.

1) it looks like the WMS UserAgent "MapServer/4.10 lubcurl..." is being blocked by jpl. I modified the source to maphttp.c and mangled the user agent string - the 403 message went away and I got an image! Well I got the image into the web.tmp directory.

2) then mapserver crashed trying to process the png RGBA wms image into map image.

3) So I tried jpeg format and it responded with:
msDrawMap(): WMS connection error. Failed to draw WMS layer named 'global_landsat'. This most likely happened because the remote WMS server returned an invalid image, and XML exception or another unexpected result in response to the GetMap request. Also check and make sure that the layer's connection URL is valid. drawJPEG(): Unable to access file. Only grayscale JPEG images are supported.

4) So I tried tiff format and it responded with:
msDrawMap(): WMS connection error. Failed to draw WMS layer named 'global_landsat'. This most likely happened because the remote WMS server returned an invalid image, and XML exception or another unexpected result in response to the GetMap request. Also check and make sure that the layer's connection URL is valid. drawTIFF(): Image handling error. Only colormapped and grayscale images are supported.

5) the issue with wms_styles looks like a code bug after reading through the code, if I understand it correctly. I have written a bug:
   http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1974
if anyone in interested in it.

So something is borked!

Can anyone get this mapfile to work with any wms connection on 4.10?

percy,

Thanks, but that does not seem to work for me. On 4.6.2, which has WMS server but does not list WMS client, or 4.10 which has support for both. "wms_styles" does not seem to get picked up and added to the url but if I add the styles= to the CONNECTION url it fails with the 403 error, but if I copy and paster the url from the debug log into the browser I get the expected image.

I think this is another bug.

Can anyone else test this and let me know if they can reproduce it. I am wondering if jpl is blocking the Mapserver client?

Here is a test mapfile:

MAP

      "wms_server_version" "1.1.1"
      "wms_format"         "image/png"
    END
  END

END

Any WMS experts online, I still haven't figured this one out.

Is it just me or has the list been pretty quite lately?

Hi all,

Just downloaded and built mapserver 4.10 and I'm have a strange problem with a WMS Layer.

The apache error log says:

If I load the URL directly into the browser is returns fine, but from mapserver I get

HTTP: HTTP GET request failed with status 403 () ... from above.

The layer definition looks like:

  LAYER

    TYPE RASTER
    DEBUG TRUE
    STATUS DEFAULT
    CONNECTION "http://wms.jpl.nasa.gov/wms.cgi?STYLES=";

      "wms_server_version" "1.1.1"
      "wms_format"         "image/png"
    END
  END


MapServer version 4.10.0 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT INPUT=TIFF INPUT=EPPL7 INPUT=JPEG INPUT=POSTGIS INPUT=SHAPEFILE DEBUG=MSDEBUG

Anyone have a clue on what I'm doing wrong, or is this a bug?

Thanks,
