Yes we used the plugin with geoserver 2.2.4 and we did not overwrite the
original jars. Our error was due to the jython jar delivered with the
geoserver python plugin was based on Java5 and we are using Java7. Maybe yours
is a geotools jar missing/mismatch issue?? The jar containing
org/geotools/process/feature/gs/SimpleProcessingCollection is the
gt-process-feature.jar

Hi Dominique,
Thanks for this information.
I assume you also have the WPS plugin installed? And did you let the WPS plugin
overwrite original JAR files? (I did not)
I tried your solution following the steps (using geoserver 2.3.0 instead) and
replacing jython but curiously I ended up having the error you described
yourself:
java.lang.RuntimeException:
java.io.IOException: javax.script.ScriptException: ImportError:
No module named types in
/var/data/tomcat7/webapps/geoserver/data/scripts/wps/mybuffer.py
at line number 1 at
org.geoserver.script.wps.ScriptProcessFactory.getDescription(ScriptProcessFactory.java:112)

at
org.geoserver.wps.web.WPSRequestBuilderPanel$5.onUpdate(WPSRequestBuilderPanel.java:225)
Seems it is really a 2.3 problem with jython?
(For the record: I also tried nightly war files with the plugins.)
Regards,
Tom

Hi Tom
We were having problems with the python scripting hook too. It turned out
to be jar compatibility. I'm not sure if it's the same problem but here's our
error and how we solved it.
Error:
Caused by: java.io.IOException: javax.script.ScriptException: ImportError:
No module named types in /h/data/gis/geoserver/external/scripts/wps/buffer.py
at line number 1
Solution:
Install geoserver pyhton and javascript scripting hooks
<initial assumptions - jboss7, java7, geoserver 2.2.4)
1) undeploy geoserver
2) download geoserver python and javascript scripting extensions from
http://gridlock.opengeo.org/geoserver/2.2.x/community-latest/
3) copy both zip files into directory <jboss deployment
dir>/geoserver.war/WEB-INF/lib
4) extract both zip files (if prompted to replace, select 'N')
5) in WEB-INF/lib, delete jython-2.5.2.jar
6) access jython download page (http://www.jython.org/downloads.html).
Download jython 2.7b1 standalone
7) cp jython-standalone-2.7-b1.jar <jboss deployment
dir>/geoserver.war/WEB-INF/lib
8) deploy geoserver
9) create scripting hooks
cd <geoserver data dir>
cd scripts/wps
create buffer.py (code found at
http://docs.geoserver.org/latest/en/user/community/scripting/hooks.html)
10) test python hook

I just installed SUN JAVA 1.6 JRE, but the problem persists. Here's a
snippet from the error log:
2013-03-27 15:53:58,962 WARN [imagemosaic.ImageMosaicFormat] -
java.lang.RuntimeException: java.io.IOException: javax.script.ScriptException:

Line 1 in mybuffer.py reads:
from geoserver.wps import process
Java info:
Sun Microsystems Inc.: 1.6.0_43 (Java HotSpot(TM) 64-Bit Server VM)
(using Tomcat7)
As far as I understand the imagemosaic has nothing to do with this, the
exception shows up a couple of times at different points in the startup of
geoserver on Tomcat7.

Hi,
It is for sure good to test with OpenJDK and Oracle 1.7 JDK, but
Geoserver has some known issues with both of them and Oracle 1.6 jre is the
officially supported version. Probably it would be more pleasure to test with
that first.

Yes, I can see the WPS among the WCS/WFS/WMS services in the left of the
menu and my handcrafted python process that I have put in ./data/scripts/wps/
is displayed in the list of WPS processes (py:mybuffer)
By the way, I have OpenJDK installed.
At the moment I'm testing with Oracle 1.7 JDK and that gives me a
javax.script.ScriptException: ImportError: cannot import name process in
/var/data/tomcat7/webapps/geoserver/data/scripts/wps/mybuffer.py at line number

It's a slightly different server though with Oracle JDK, so I'm testing
some more.
