I was wondering the same thing, until I found this:

Jython FAQ Entry
3.9. The Jython's os module is missing some functions, why?

 Python's and Jython's os modules differ necessarily because
of differences Java imposes on natvie system access. For
example, Java does not have a chdir equivalent, so it does
not exist in Jython's os.

There is an alternative os module that does provide
additional functionality, and it is the jnios module found at:

http://sourceforge.net/projects/jnios

The jnios module replaces the default os module with a
Java/JNI implementation of Python's os and posix modules.
"""

I have no idea whether you can get jnios to work with a
modern jython 2.1, however.
