[ZOO-Discuss] Error when running GRASS processes

Tue May 3 20:23:16 PDT 2011

Hi Soeren,

Thanks, it seems to work: I'm bumping into the same error as you now!

root at grass:/usr/local/src/wps-grass-bridge-read-only/Testing/Python#
python SendRequests.py -f ExecuteRequests/v.voronoi.execute.xml -u
"http://localhost/cgi-bin/zoo_loader.cgi"
Start request 0

  <ows:Exception exceptionCode="InternalError">
    <ows:ExceptionText>ZOO Kernel failed to process your request

  </ows:Exception>
</ows:ExceptionReport>

If that could be of any help, I had to recompile GDAL to have Xerces support.

Cheers,

Pierre
