[ZOO-Discuss] GIS GRASS ZOO integration

[Eugenio Realini]

Hi Soeren, hi Luca,

this is our situation now:

1) we have re-generated the WPS.1.0.0 python modules with PyXB 1.1.1,
this solved the problems we had with it
2) we faced the Xerces issue Soeren was talking about, so we
recompiled GDAL with it and also this was solved
3) launching "python ZOOGrassModuleStarter.py" does not give any error
4) launching "r_univar" through ZOO gives us this exception:

<ows:ExceptionText>
TRACE : invalid literal for int() with base 10: 'NULL'
TRACE : <type 'exceptions.ValueError'>
Unable to run your python process properly. Please check the following
messages : ['  File "/usr/lib/cgi-bin/r_univar.py", line 4, in
r_univar\n    service.fromMaps("r.univar", inputs, outputs)\n', '
File "/usr/lib/cgi-bin/ZOO_Project/ZOOGrassModuleStarter.py", line
110, in fromMaps\n    self._createInputOutputMaps()\n', '  File
"/usr/lib/cgi-bin/ZOO_Project/GrassModuleStarter.py", line 214, in
_createInputOutputMaps\n    self._checkBandNumber()\n', '  File
"/usr/lib/cgi-bin/ZOO_Project/GrassModuleStarter.py", line 331, in
_checkBandNumber\n    self.bandNumber = int(self.inputMap[i])\n']
</ows:ExceptionText>

To my understanding, it does not like getting 'NULL' as
'grass_band_number', since it expects an integer.

You can read the contents of the logfile here: http://pastebin.com/pxG1VVaz

This is the link to the r_univar execute request:
http://131.175.143.108/cgi-bin/zoo_loader.cgi?Service=WPS&Request=Execute&Version=1.0.0&Identifier=r_univar&DataInputs=map=DTM_108.tif

Any idea on how to proceed from here?
Thanks!
Eugenio
