Just a tip. If you do this, you won't have to call login 2x:

use SOAP::Lite;
use HTTP:: Cookies;

my $COOKIE       = './coooooooooookie.txt';
my $SET_COOKIE   = HTTP::Cookies->new(ignore_discard => 1,
                    file=> $COOKIE, 
                    autosave=>1);


my $soapLite = SOAP::Lite->new();
$soapLite->proxy($end_point, cookie_jar => $SET_COOKIE);
$soapLite->uri($uri_slash_method);

I've had success putting that (plus other pertinent info) into a _call method, then constructing separate methods that are called through _call. Hope that helps.
