SOAP document/literal Server

Norret has asked for the wisdom of the Perl Monks concerning the following question:

Hi everyone! I've implemented a SOAP Perl server for rpc/encoded SOAP messages. My client was a C# application, everything worked fine, till I had to use document/literal SOAP messages. So I created a new WSDL file in document/literal style using the package WSDL::Generator. On the server side I use SOAP::Transport::HTTP; to dispatch the SOAP Query to the correct function. My problem now is, that the SOAP message from the C# client arrives at the server, but without the parameters. I hardly searched google for a tutorial with document/literal message, but can't find anything useful. To make it clearer, I will attach some source:
Client (C#)

static void Main(string[] args)
        {
            try
            {
                ProxyLicenceService service = new ProxyLicenceService(
+);
                string licence = service.generateProxyLicence("blubb")
+;
                Console.WriteLine(licence);
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
            }
        }
[download]

Server (Perl):

SOAP::Transport::HTTP::CGI   
    -> dispatch_to('proxyLicenceService')     
    -> handle;

package proxyLicenceService;

=begin WSDL

=cut
sub generateProxyLicenceRequest
{
    #my @params = split(/;/,$_[1]);
    my $test = $_[1];
    system("echo $test >> C:\\www\\htdocs\\cgi-bin\\test.log");

}
[download]

$_ [0 ] contains the name of the package
$_ [1 ] is empty, but should contain "blubb" :(

Thanks for your help!
