Hi
i just updated my VM to java1.7, geoserver 2.2.4 and the python scripting hook
from http://gridlock.opengeo.org/geoserver/master/community-latest/
I unzip the contents of the python scripting zip file to my
geoserver/WEB-INF/lib directory and restarted the server.
I see the created scripts/wps folders under my geoserver data dir, and added
the buffer.py file from the example page
http://docs.geoserver.org/stable/en/user/community/scripting/hooks.html under
the wps folder and made sure it had the correct permissions.
I do not see the the py:buffer in the WPS get capabilities document
http://localhost:8080/geoserver/ows?service=wps&version=1.0.0&request=GetCapabilities
but I do see it under the WPS Request Builder dropdown which is odd.
When I try to run the wps via the following rest call and when I hit the
py:buffer wps in the dropdown on the WPS builder request page i see the
following error in the geoserver logs:
http://localhost:8080/geoserver/wps?service=WPS&version=1.0.0&request=Execute&identifier=py:buffer&datainputs=geom=POINT%280%200%29@mimetype=application/wkt;distance=10

Heres the buffer.py contents
from geoserver.wps import process
from com.vividsolutions.jts.geom import Geometry
@process(
title='Buffer',
description='Buffers a geometry',
inputs={
'geom': (Geometry, 'The geometry to buffer'),
'distance':(float,'The buffer distance')
},
outputs={
'result': (Geometry, 'The buffered geometry')
}
)
def run(geom, distance):
return geom.buffer(distance);
The python scripting app directory works. If I add a hello world app under
data_dir/scripts/apps/hello/main.py and hit it via a rest call I see the
correct output. Although I had to create the apps directory myself the python
scripting hook created a functions directory. So it just seems that its the
wps python scripting function that isnt working.
Do I need to add a geoserver.wps jar to the lib directory under
data_dir/scripts/lib ?
Do I need to add geoscript python jars? http://geoscript.org/py/
Thank You
Dominique

Hmmm... ok. What version of Geoserver and the scripting extension are you
running?

It looks like this. It’s the same one as the example

Hmmm... any chance you can make the script available, I can take a closer look.

Hi
I’m having trouble installing the python scripting hook. I unzip the contents
of geoserver-2.2-SNAPSHOT-python-plugin.zip into my geoserver-2.2/WEB-INF/lib
file. In my GEOSERVER_DATA_DIR is see a scripts/lib and scripts/function
directory. I created a scripts/wps directory and made the buffer.py example
from http://docs.geoserver.org/stable/en/user/community/scripting/hooks.html
When I go into the WPS request builder and try to run the buffer.py script I
see the following error in geoserver.
15:46:38,593 ERROR [org.apache.wicket.RequestCycle] (http--0.0.0.0-8080-1)
java.io.IOException: javax.script.ScriptException: ImportError: No module named
types in /gis/geoserver/external/scripts/wps/demo.py at line number 1:
java.lang.RuntimeException: java.io.IOException: javax.script.ScriptException:
ImportError: No module named types in
/gis/geoserver/external/scripts/wps/demo.py at line number 1
Line number 1 is
from geoserver.wps import process
what am I missing?
Thank you
