Hi @all,
has someone successfully realized an WMS with UTF-Grid-Layer?
(http://mapserver.org/development/rfc/ms-rfc-93.html)
I use Mapserver 7.0.0 (and also tried the latest master) and wasn't able to get
any output from the web-Service as WMS-Request with format "application/json".
The application/json-response has a filesize of 0Bytes, other formats
(jpeg/png) work well - with exactly the same request, except the format.
UTF-Grid also seems to be produced well with a simulated request against
mapserver on the commandline-interface
("/usr/local/bin/mapserv
QUERY_STRING="SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=339444,5697190,347678,5702286&CRS=EPSG:25832&WIDTH=1556&HEIGHT=963&LAYERS=poi
&STYLES=&FORMAT=application/json&TRANSPARENT=TRUE&map=PATH_TO_MAPFILE" >
OUTPUT")
Mapserver LOG (DEBUG 5) with wms request:

--> I would say, this looks good, but no response on the client-side!
Some further investigation showed me, that the correct output is written to the
apache error.log!!!
I'm not a developer of web application/cgi etc, but comparing this to writing
shell scripts (which I do a lot), it seems, that the mapserver output for
format "application/json" goes to "STDERR" (apache error.log) and not to
"STDOUT" (client)
System is debian7, apache 2.2, mapserver 7/master (self compiled, as well as
the geos-/gdal-/proj-stack).
Could someone crosscheck this feature, does it need special apache-config? Is
it a misconfiguration of apache or a mapserver/apache-bug?
Any ideas out there?
Thank You very much
Ben
