Can I ask you what your development environment looks like when you tested the python scripting hooks and then I can recreate it here? Again the javascript hook works it's just the python hook.
What version of geoserver? What version of the python hook? What Application Server? Etc.

I wonder if Java 7 might be the issue, i know from time to time things are found not to work with it, it could be something in javax.script that has changed. Or perhaps something related to invokedynamic that was added in java 7. It would interesting if you could try on java 6 to see if the problem still exists, that way we can at least rule it out.

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.

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 _____ From: Justin Deoliveira [jdeol...@opengeo.org] Sent: Thursday, February 07, 2013 8:26 AM To: Bessette-Halsema, Dominique E Cc: geoserver-users@lists.sourceforge.net Subject: Re: [Geoserver-users] python scripting hook Hmmm... ok.
