Re: Import Error: No module named os

Hi,

I am currently working on a web application which allows user to upload/run
python script in web application. I copied jython-standalone-2.7.0.jar to
WEB-INF/lib and build web application as war file. however, I get a
following error when running a python script:

org.python.core.PyException: null

I found a workaround by running jython installer and setting python.home by
specifying -Dpython.home=<jython install directory> as a JVM parameter. I
think the purpose of using jython-standalone-2.7.0.jar is to be able to run
jython without running installer.

How do I specify jython-standalone-2.7.0.jar as python.home? I think
somehow it needs Lib directory which is inside of jar.


Any recommendations are appreciated. Thanks

John
