Hi Team,

I want to import requests, json module in my java code .
I have installed Jpython on unix & also installed requests module as well .
My code is like :
pythonInterp.exec("sys.path.append(\"/home/ec2-user/yogita/jpython/Lib/site-packages\")");
		pythonInterp.exec("print (sys.path)");
		pythonInterp.exec("import requests");

And output is like 
['/home/ec2-user/yogita/jpython/Lib', '/home/ec2-user/yogita/jpython/Lib', '__classpath__', '__pyclasspath__/', '/home/ec2-user/yogita/jpython/Lib/site-packages', '/home/ec2-user/yogita/jpython/Lib/site-packages']
Exception while importing python module: Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named requests
 

/home/ec2-user/yogita/jpython/Lib/site-packages

It works for me at the prompt (Windows 10, Jython 2.7.2b2, pip 19.1), on a clean installation:

PS issue2852> inst\bin\pip install requests
...
PS issue2852> inst\bin\jython
Jython 2.7.2b2 (v2.7.2b2:b9b60766cabe, Nov 1 2019, 07:46:45)
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.8.0_231
Type "help", "copyright", "credits" or "license" for more information.
>>> import requests
>>> import sys
>>> sys.path
['', '...\\issue2852\\inst\\Lib', '__classpath__', '__pyclasspath__/', '...\\.local\\lib\\jython2.7\\site-packages', '...\\issue2852\\inst\\Lib\\site-packages']

And the same from Java. On a quick check, also good on Jython 2.7.1. Argument -v to Jython will give you more information about where it looks during import (and -vv even more).

You don't need to work so hard on the sys.path: you can see Jython has already done it.
