missing modules

[Tracy12 <j_...@yahoo.com>]

Hi,

I have the following piece of code within  my perl module, intention is to
update the REMOTE_USER variable.

I am using apache 2.2 with mod_perl 2.0 on Fedora core 5.

 $r->connection->user($user2);

but at run time it gives the following error.

 Can't locate object method "connection" via package "Apache2::RequestRec" 

which package should I really import is it Apache2::Connection () I tried
this and it says cannot find Connection object.

How to proceed on this.

Hi,
	I made a test with your code, yes it works,
But I have other things to ask:


Script1:
package PrintIp;

#use mod_perl2 ();
use Apache2::Const qw(:common);
#use Apache2::Request ();
use Apache2::RequestRec ();

sub handler {
        my      $r= shift;
        #my     $apr= Apache2::Request->new( $r );
        my $c = $r->connection;
        $r->print($c->remote_ip());
        return Apache2::Const::OK;
}

1;

Script2:
package PrintIp;

#use mod_perl2 ();
use Apache2::Const qw(:common);
use Apache2::Request ();
use Apache2::RequestRec ();

sub handler {
        my      $r= shift;
        my     $apr= Apache2::Request->new( $r );
        my $c = $apr->connection;   #different
        $r->print($c->remote_ip());
        return Apache2::Const::OK;
}

1;

Q: why both of the two script works? And I found the remote_ip method is in
Apache2::Connection, I never 'use' it, but I can call its method,
The Apache2::Request "use" it for me ?

I guess the $apr can call connection because it is base on $r.

Mod_perl objects sometimes very confuse to me, for example: the
Apache2::Connection pod only say :$c->method, but what is $c?
I only guess it is $c = $r->connection,(or you can say research the src
code)
Is there something like a big picture show the relationship between the
mod_perl2 related objects?


Thanks!
