I'm creating a Java application and will best work if I incorporate Python in it. I'm having jython-standalone-2.7.0.jar lib. My question is, how do I use this lib like create a simple hello world application written in Python and display the output in java? I have Python 3.5 installed. Do I need it too or is there anything else I need? Please help, thanks.

if you're still interested in an answer:
0) Jython isn't supporting Python 3 (so far), only Python 2.7.
1) Create a Python file with a function f.e.:
#hello.py
def printhello():
print("Hello World from hello.py")
2) Unzip your jython-standalone-2.7.0.jar and add your "hello.py" file into the folder "Lib".
3) Close your jython-standalone-2.7.0.jar again
4) Create your "main file":
#main.py
import hello
print("Hello from main file")
hello.printhello()
print("I'm back in main")
And add it into the same file where your standalone.jar is.
5) In your terminal/cmd execute: java -jar jython-standalone-2.7.0.jar main.py
6) Success (I hope ;-) )
P.S. If you're using Windows, don't use the OS own zip methods, because in my case my jar file was rubbish afterwards.

Is there a way to execute the script when the jython-standalone*.jar has been extracted? I am trying write a plugin for an application which deploys jython-standalone in folder format (instead of inside the .jar).
