Rubyzip and java.util.zip.ZipFile interoperability issue

Rails
1

All,

Going out on a limb here but thought I would ask.

I am generating a ZIP file from a Rails app. with Rubyzip 0.9.1. The
app. runs on a Mandrake Linux box which writes to a Windows filesystem
via a Samba mount.

Later, a Java program comes along and uses java.util.zip.ZipFile (JDK
1.5) to open this ZIP file. Lately I’ve been seeing read exceptions on
these ZIP files.

Anyone ever seen a case where Java had a problem reading a Ruby
generated ZIP file before?

Granted I have lots of other moving parts here so…

Thanks,
Wes

IIRC, I had problems with ruby-zip in one of my apps too (i know i
had to look for other option, but i can’t remember why), I just
switched over to the shell with the zip and unzip command (just put
everything in a temp folder, then zip it using the shell). Runs
smoother and faster than ruby-zip.

Peter,

I definitely considered that and am glad to hear that it worked.

As it turned out, I was creating and appending to the zip file directly
on that remote SAMBA mount, so instead what I did was create the ZIP
file locally, and then copied it to the remote SAMBA mount using
FileUtils and that seems to work much better.

In fact, I had had the same issue with another part of that same app.,
and just hadn’t applied the fix across the board.

Thanks for the response.

Wes
