Try this:

<code>
import os
from os.path import dirname, exists, splitext, join
from zipfile import ZipFile, ZIP_DEFLATED

def unpack(archname):
    arch = ZipFile(archname, 'r')
    for path in arch.namelist():
        print path
        dname = dirname(path)
        if not exists(dname): os.makedirs(dname)
        if splitext(path)[1]:
            f = open(path, 'wb')
            f.write(arch.read(path))
            f.close()
    arch.close()

def pack(archname, paths):
    arch = ZipFile(archname, 'w', ZIP_DEFLATED)
    for path in paths:
        for root, dirs, files in os.walk(path):
            for fname in files:
                fname = join(root, fname)
                print fname
                arch.write(fname)
    arch.close()

unpack('test.jar')
pack('test2.jar', ['com', 'META-INF'])
</code>
