At first I'll say sorry that have no experience for writting the modperl
When I wrote a simple handler like:

$ cat CorpFB/
package CorpFB::Feedback;
use Apache::Constants qw(:common);
use strict;
use Apache::Request();

sub handler {

my $r = shift;



return OK;


The CorpFB/ is under the directory of '/home/apache1.3/cgi'
which exist in the

$ cat lib/
use strict;

use lib '/home/apache1.3/cgi';
$ENV{MOD_PERL} or die "not running under mod_perl!";

Here are the modperl config pieces in my httpd.conf:

PerlRequire /home/apache1.3/cgi/lib/
Alias /fbl/ "/home/apache1.3/fbl/"
PerlModule CorpFB::Feedback

SetHandler perl-script
PerlHandler CorpFB::Feedback

Ok,when I access the url with:

I got the errors in error_log:

[Thu Sep 28 16:32:53 2006] [error] Undefined subroutine
&CorpFB::Feedback::handler called.\n

Could you help me with it?Thanks.
