Would anyone care to suggest favoured tools for manipulating the
innards of JARs? Or do I just treat them as plain zipfiles and get
stuck right in there?
Mainly I'm trying to query lists of classes and their embedded
versions and do some library dependency reporting. Performance speed
is starting to be an issue, as there's 1500+ classes in this bucket
and it's an interactive query.
I believe that you can rename any jar file to .zip and use zip tools to
list its contents.
Laszlo
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
