To print out the classes you can use zipfile
it will list the contents of a jar file also
import zipfile
zf = zipfile.ZipFile("some.jar")
for info in zf.infolist():
print info.filename
Or print to a file
import zipfile
zf = zipfile.ZipFile("some.jar")
for info in zf.infolist():
classes = info.filename
myfile = file("classes.txt", 'w')
print >> myfile, classes
Enjoy
