I'm trying to edit the MANIFEST.MF file in a .jar application using Archive::Zip

I'm not sure if I am going about it the right way. I'm reading and editing the file, printing the revised file externally. I've made a few attempts to get the new file to replace the file in the app but without success, the new app being identical to the original!

#!/usr/bin/perl -w
use strict;
use CGI::Carp qw(fatalsToBrowser warningsToBrowser);
use CGI ':standard'; 

print "Content-type: text/html\n\n"; 

my $file = 'MANIFEST.MF';

  use Archive::Zip;
  use Archive::Zip::MemberRead;
  my $zip = Archive::Zip->new("MyWeb.jar");
  my $fh  = Archive::Zip::MemberRead->new($zip, "META-INF/MANIFEST.MF"
+);
  
  open FH, '>', $file or die $!;
  
  while (defined(my $line = $fh->getline()))
  {
      chomp $line;
      if ($line =~ /id=(.*)$/) {
        $line =~ s/$1/1012/;
        print FH "$line\n";
        print "$line\n";
      } else {
        print FH "$line\n";
        print "$line\n";
      }        
  }

my $member1 = $zip->replaceMember( 'MANIFEST.MF', $file );


$zip->overwriteAs('file.jar');
