in reply to SOAP and .NET

SOAP as a transport is best not debugged at all :-)

The .NET web-service should be publishing a WSDL description of what the service expects. Clients of the service need merely translate the WSDL into "proxy" methods of the service.

Even though my script runs with apparently no errors, the other end is saying nothing is coming through.
How exactly is the "other end" saying this? That you're script runs with "no errors" is probably meaningless, as you'd need to explicitly handle any SOAP fault objects that are sent back to the client.

In the worst case, you can turn on debugging in SOAP::Lite to see what is being sent to and received from the .NET service.

On the perl client side, I absolutely recommend SOAP::WSDL as it does almost all of the hard work for you; you'll get much more meaningful errors before you see the few exceptions to this.

SOAP::WSDL is a sub-class of SOAP::Lite, the module used by the vast majority of perl SOAP clients/services.

    Thanks for the pointers, I'll look at SOAP::WSDL. I've discovered that I have to use SOAP::Lite for my 'client' script, and SOAP::Transport::HTTP for the 'server' script. I have debug on, and in my client log get this:

    SOAP::Lite::call: ()
    SOAP::Serializer::envelope: ()
    SOAP::Deserializer::deserialize: ()
    SOAP::Parser::decode: ()
    which of course helps me tremendously :)

    The programmers running the .NET side are telling me that nothing is coming through, so until I get the debugging thing working I'm at their mercy.

      I've managed to get some debugging information, but it leaves me no closer to a solution:

      mismatched tag at line 61, column 16, byte 2902:
      <p>
             </ul>
      ====^
      </span>
      at C:/usr/lib/XML/Parser.pm line 187

      Of course looking at the Parser module sheds no light on where / how that HTML code is being generated. Line #187:

      $result = $expat->parse($arg);

      I'm spiralling further away from a solution here and could really use some help.

      My code

      use SOAP::WSDL +trace => qw(dispatch);
my $soap = SOAP::WSDL->new(wsdl => 'http://xxx.xxx.xxx/somedoc.asmx');
+ # edited
$soap -> wsdlinit();
$soap -> servicename('Web Mechanic');
my $transport = $soap -> call('Insert' => (
Firstname => $FirstName )); # previously defined

        That's not a valid XML fragment for starters.

        use SOAP::WSDL +trace => qw(dispatch);
my $soap = SOAP::WSDL->;new(wsdl => 'http://xxx.xxx.xxx/somedoc.asmx')
+; # edited
$soap -> wsdlinit();
$soap -> servicename('Web Mechanic');
my $transport = $soap -> call('Insert' => (
Firstname => $FirstName )); # previously defined

        Why are you calling the 'call' method of SOAP::WSDL? That's SOAP::Lite silliness.
        Call the methods exposed by the remote service instead.
