Thank you!

I've used Pod::WSDL as you sugested but I still get the error, however I've managed to find something that I think might be the issue.
First of all, this is my new code:

WebserviceFunctions.pm

package WebserviceFunctions;

=begin WSDL
_DOC Hello
_IN name $string this is the name
_OUT text $string return text
=end WSDL


sub Hello {
    my ($s, $name) = @_;
    return "Hello, $name".$/;
}

=begin WSDL
_DOC Goodbye
_IN name $string this is the name
_OUT text $string return text
=end WSDL

sub Goodbye {
    my ($s, $name) = @_;
    return "Goodbye, $name".$/;
}

webservice.cgi

#!/usr/bin/perl -w

use Pod::WSDL;
use CGI;

print CGI->header('text/xml');

my $pod = new Pod::WSDL(source=> 'WebserviceFunctions.pm',
                        location=>'http://192.168.11.73/~efuentes/webs
+ervice',
                        pretty=>1,
                        withDocumentation=>1);

$pod->addNamespace('http://192.168.11.73/~efuentes/webservice/','Webse
+rviceFunctions');

print $pod->WSDL;

Now, you can see the full address where I generate the Webservice is "http://192.168.11.73/~efuentes/cgi-bin/webservice/webservice.cgi", if I put that on my browser I get my wsdl, but now, I've found in that wsdl this code "targetNamespace="http://192.168.11.73/WebserviceFunctions" wish differs from my full path, I've tried to change it with "$pod->addNamespace('http://192.168.11.73/~efuentes/webservice/','WebserviceFunctions');" as you can see in the code, but I get the same targetNamespace on the wsdl.
Any suggestions to fix that?
