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] -

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 1
It's a slightly different server though with Oracle JDK, so I'm
testing some more.
Chrs, Tom
