Re: Edit Manifest file in jar archive

[almut]

$zip->replaceMember( 'MANIFEST.MF', $file );

Maybe try instead

$zip->replaceMember( 'META-INF/MANIFEST.MF', $file );

Also, it seems (though the docs are somewhat ambiguous) the method wants a member object for the new member, not a file name, so try  (untested)

...
my $new_member = Archive::Zip::Member->newFromFile($file);
$zip->replaceMember( 'META-INF/MANIFEST.MF', $new_member);

If that doesn't work either, what's the return value of replaceMember()? (according to the docs, it returns undef on error)

This is almost right, but then the zip file will contain a file 'MANIFEST.MF' instead of 'META-INF/MANIFEST.MF'. I think updateMember will work, though. Also, you need to close FH;

So,

  close FH or die "error writing $file: $!\n";
  $zip->updateMember('META-INF/MANIFEST.MF', $file)
    or die "updateMember";

Thanks very much for your input. This is definitely on the right lines - it is getting the required file into the app but in the wrong place!!

I have an empty META-INF directory (so Manifest file is being deleted, but alongside that (in the main directory) the MANIFEST.MF file. I will now need to discover how to move the file into the directory. Thank you once again.
