Many thanks, Daniel & Tõnis, for both of your replies!
The GeoServer 2.11.2 uses Jython-2.5.0.jar that is saved in the "WEB-INF/lib".
I don't know how to install new packages into this jar file so that GeoServer
can use them.
I actually ended up with installing the most recent standalone Jython-2.7.0 on
my computer. I was able to run easy_install or pip off the standalone Jython to
install a couple of packages. Each py file installed for the new packages comes
with a class file. This is different to native Python. I then managed to copy
the resulted package folder to GeoServer's "\scripts\lib\py".
I think this is my only way to install new packages for GeoServer to use. As
said above, I don't know how to install packages to the Jython jar file without
having to use the standalone Jython. Could someone direct me?
In terms of the "requests" package, I am still having trouble installing
through pip or easy_install off the standalone Jython.
C:\jython2.7.0\bin>pip install requestsTraceback (most recent call last): File

Google search suggested this package does not have a java port... Very weird.
- Daniel, you mentioned that "from Jython we can use Java networking
libraries". Can you elaborate it in details please? How can I use 3rd Java libs
in writing a GeoServer custom app or a web processing service in Python or
JavaScript as I would like to stick with Python/JavaScript?
Cheers,Alex

Alex you should be able to do normal python package installs using jython, e.g.
https://stackoverflow.com/questions/6787015/how-can-i-install-various-python-libraries-in-jython
You use jython to run easy install, then you can jython easy-install pip, then
you can jython pip install whatever you want. You might need to search around a
bit to find the jython that geoserver uses, but it sounds like you've found its
location already.
It won't work for libraries that compile their own binaries, but I think
Requests is pure python so should work fine.
Also, remember from Jython you can use Java networking libraries, so you
mightn't need Requests.

Hi Tõnis,
Thanks for the info.
I know the pip way to install new packages on native Python. But GeoServer does
not seem to use the native Python on the OS but Jython in the WEB-INF/lib. I
tried to copy the installed package to "{GEOSERVER_DATA}/scripts/lib/py/" and
restarted GeoServer. I imported the package in the Python script and copied the
file to "{GEOSERVER_DATA}\scripts\apps\hello\main.py". When I called the app
url via HTTP as instructed in the documentation, it complained about "unable to
find the module xxx".
Hope someone could give any clue about it.
Thanks.
Cheers,Alex

Hey Alex,
You can use e.g pip https://pip.pypa.io/en/stable/ but I guess any
Python package manager will do. With pip it would be smth like:
pip install packagename -t /the/path/you/want
Maybe there's a way through simply setting environment variables
aswell to use your existing modules. But not really sure, I don't know
enough about jython/java for that matter.
All the best,
Tõnis
