setting CLASSPATH in Python?

[Matt Dorn]

Hi all,

I have a Python script that looks like this:

import os

from jnius import autoclass

javapath = ".:/path/to/jar_files/*"

os.environ['CLASSPATH'] = javapath

print 'CLASSPATH: ', os.environ['CLASSPATH']

adb = autoclass('com.android.ddmlib.AndroidDebugBridge')

print 'adb obj: ', adb

When I run it, it fails like so:

user@host:$ python foo.py 

CLASSPATH:  .:/path/to/jar_files/*

Traceback (most recent call last):

  File "bin/python", line 33, in <module>

    execfile(__file__)

  File "ve_android/bar.py", line 9, in <module>

    adb = autoclass('com.android.ddmlib.AndroidDebugBridge')

  File "/usr/local/lib/python2.7/dist-packages/jnius/reflect.py", line 109, in autoclass

    c = find_javaclass(clsname)

  File "jnius_export_func.pxi", line 23, in jnius.find_javaclass (jnius/jnius.c:7134)

jnius.JavaException: Class not found 'com/android/ddmlib/AndroidDebugBridge'

But if I set CLASSPATH manually in the shell, and then run it, it works:

user@host:$ export CLASSPATH=".:/path/to/jar_files/*"

user@host:$ python foo.py 

CLASSPATH:  .:/path/to/jar_files/*

adb obj:  <class 'jnius.reflect.com.android.ddmlib.AndroidDebugBridge'>

I would have expected my Python os.environ manipulations to have the same effect as exporting the env var in the shell, but no such luck.  Any ideas?

Thanks,

Matt

I think you need to do it _before_ importing jnius.
Once it's imported, the java internal is already imported, so it's over.

Did you try to push the os.environ before the import ?

Thank you Mathieu for the lightning-quick response -- that worked!
