I am new to Salesforce and SOAP development and having a bit of trouble getting started. I am not sure how I can employ the enterprise.wsdl file so I can start inserting (creating) records for my objects. I've tried, unsuccessfully, to change the Salesforce.pm itself from:

    my $client = SOAP::Lite
        ->deserializer(Salesforce::Deserializer->new)
        ->on_action( sub { return '""' } )
      ->uri('urn:partner.soap.sforce.com')
     ->proxy($self->{address});

to:

    my $client = SOAP::Lite
        ->service('file:/usr/local/lib/perl5/site_perl/5.8.5/enterprise.wsdl');

I am trying to test an insert (code 1 below) but get errors (error 1 below). The reason I thought I needs the wsdl file change in the module because before I was getting some errors without it.

code 1:

#!/usr/local/bin/perl
use CGI;
use CGI::Carp qw(warningsToBrowser fatalsToBrowser);
use Net::LDAP;
use Net::SMTP;
use SOAP::Lite;
use Salesforce;
use Data::Dumper;

        my $service = new Salesforce::SforceService;
        my $port = $service->get_port_binding('Soap');
        $port->login('username' => 'myusername@mycompany.com','password' => 'secret')
           || die "Could not login to salesforce.com";

        my @results = $port->create( 'type' => "Case",
                                'Contact_Info__c' => "test contact",
                                'Subject' => "test subject",
                                'Version_of_system__c' => "1.0",
                                'Reproduction_Steps__c' => "test 1 2 3",
                                'Always_Reproducible__c' => "true",
                                'What_you_expect_to_see__c' => "expectation",
                                'Expected_behavior_in_documentation__c' => "docsupportexistsval",
                                'Documentation_Reference__c' => "docsupportref",
                                'Additional_Information__c' => "additionalinfo" );
        foreach (@results) {
        print Dumper($_->result);
        }

error 1:
