Gonzalo, 

It looks like you have corrected the original error.  You were trying to use a shape file as the data source for a raster layer.  

Now, you have changed the layer type to polygon and you are getting a different error.  You also didn't mention that you were using pmapper.  

I recommend stripping down your map file to the bare case needed to get it working.  Then, you can add back complexity and determine if the problem lies in your map file or if it is somewhere else.  

Try using something like this for your layer definition:

LAYER
 NAME 'Argentina'
 DATA 'argentina_gg'
 STATUS DEFAULT
 TYPE Polygon

 CLASS
  NAME 'Argentina'
  STYLE
   OUTLINECOLOR 129 0 0
  END #STYLE
 END #CLASS
END #LAYER

This assumes that you have SHAPEPATH '/home/orsep/public_html/gis/mapoteca/presas_gis/data/' in your map file.  Also, for testing purposes, get rid of all of the other layers in your map file and take any projection info out of your map file.  

Then, either use shp2img or a simple mode=map call to mapserver CGI to test your map file.  

e.g. http://127.0.0.1/cgi-bin/mapserv?mode=map&map=/home/orsep/public_html/gis/mapoteca/presas_gis/argentina.map

(Of course, you will have to modify this to point to the correct domain/ip and use the correct name of your map file.)

David.

Hi David,

The sharedpath in .map is:

SHAPEPATH '/home/orsep/public_html/gis/mapoteca/presas_gis/data/'

There are this files:

-rw-r--r--  1 orsep orsep    5216 Apr 26  2007 argentina_gg.dbf
-rw-r--r--  1 orsep orsep     636 Apr 26  2007 argentina_gg.sbn
-rw-r--r--  1 orsep orsep     172 Apr 26  2007 argentina_gg.sbx
-rw-r--r--  1 orsep orsep 1510004 Apr 26  2007 argentina_gg.shp
-rw-r--r--  1 orsep orsep     348 Apr 26  2007 argentina_gg.shx

If in the .map set this:

LAYER
 NAME 'Argentina'
 DATA 'argentina_gg'
 STATUS on
 TYPE Polygon
 TRANSPARENCY 50
 TOLERANCE 7
 TOLERANCEUNITS pixels

 METADATA
  WMS_SRS  'epsg:4326'
  WMS_TITLE 'WMSTitel'
  WMS_FEATURE_INFO_MIME_TYPE 'text/html'
 END #METADATA

 PROJECTION
  'init=epsg:4326'
 END

 CLASSITEM 'NOMBRE'

 CLASS
  NAME 'Argentina_gg.shp'
 EXPRESSION /./

  STYLE
   #COLOR 129 0 0
   OUTLINECOLOR 129 0 0
  END #STYLE
 END #CLASS
END #LAYER

I have a Internal server error whit this apache error_log message:

[Tue Jun  2 23:30:37 2009] [error] [client 190.190.4.193] Premature end of script headers: /home/orsep/public_html/gis/map.phtml

If in the .map set this:

LAYER
 NAME 'Argentina'
 DATA 'argentina_gg'
 STATUS on
 TYPE Polygon
 TRANSPARENCY 50
 TOLERANCE 7
 TOLERANCEUNITS pixels

 METADATA
  WMS_SRS  'epsg:4326'

 END #METADATA

 PROJECTION

 END

#  EXPRESSION /./

 # STYLE
   #COLOR 129 0 0
 #  OUTLINECOLOR 129 0 0
#  END #STYLE
# END #CLASS
END #LAYER

Pmapper works, but dont draw. And no apache error.

Please help me :(
