In python , I can use the following codes to open ms paint Program. 
import popen2
popen2.popen2('mspaint')

but it does not take effect in Jython 2.1
error message : 
Traceback (innermost last):

  File "d:\jython-2.1\Lib\popen2.py", line 143, in popen2
  File "d:\jython-2.1\Lib\popen2.py", line 35, in __init__
AttributeError: class 'org.python.modules.os' has no attribute 'pipe'


who can tell me the reason ?
