Creating a zip or jar file with directory structure!

[Lee]

Hi,

I am trying to (zip or jar) a directory (including empty directories)
using
java.util.zip.* and java.util.jar.*. I can create zip and jar files
but
when extracted all files appear to be in the root dir of the extracted
zip/jar. How can i keep the directory structure intact? Does anyone
have
any examples please?

thanks in advance
lee

Are you sure this is not a problem with your method of unzipping the files?

Check what Roedy Green has on that great site and as Thomas said check
your unzipping. Check the zip with a 3rd party app (a simple win
explorer will do it) and make sure you don't have the directory
structure there. If everything seems all right, check when adding the
new entry to the ZipOutputStream. It has to contain the full path you
want to see inside the zip file.

for ex:
....
ZipOutputStream zos = new ZipOutputStream(new
FileOutputStream("/test.zip"));
File f = new File("pathToMyFileToBeZipped");
//add zip entry to output stream
zos.putNextEntry(new ZipEntry(f.getAbsolutePath()));
....

use the absolute path, if you want a relative path you will do a
substring on the absolutepath and there you go

Are you sure this is not a problem with your method of unzipping the files

use winzip or other archiver to check the structure. The main problem
you run into is trying to unzip files compressed with esoteric
compression algorithms with rather dull Java classes that only know
the basic ones.
