SOAP::Lite Confusion

[gnork]

Dear monks!

I would like to use SOAP::Lite to provide the vital parts of our system functionality. However, not everyone is a perl lover. I found the WSDL::Generator on CPAN, which will be a good help on my way to make these SOAP RPC Servers talk to C/C++/PHP/Perl/whatever speaks SOAP.

While trying to figure out, how this works, I became totally confused about Namespace(s), URI, URN etc.pp. Until now there was no need to use these, since this code works under perl:

Server:

# define the routines ...
sub return_sumfink {

  #do something

}

# and 

$daemon = SOAP::Transport::HTTP::Daemon
           -> new(LocalAddr => $host, LocalPort => $port,          
                  Reuse => 1)
           -> dispatch_to('return_sumfink','aFunction')
$daemon->handle;

BTW, if you ran out of sockets with SOAP::Lite or had to wait 30secs to start a new SOAP Server (Port already in use), have a look at the Reuse option above.

Client:

$s = SOAP::Lite
     ->proxy("http://$machine:$port")
     ->on_fault(sub{});
$r = $s->test_connection;
unless (defined $r && defined $r->envelope) {
  return 'NOGO:', $s->transport->status, "\n";
}

return $s->call(@_)->result;

This worked like a charm, but now for the language independend way ... AFAIK, one way to construct the URN is using Namespaces (packages) within the Server. Lets say I defined a package ExternalIO in the server, which contains the sub return_sumfink. NOTE: I have no external modules (e.g. ExternalIO.pm), its within the server.

Now I try to call the function:

use SOAP::Lite +autodispatch =>
               uri=>'ExternalIO',
               proxy=>'http://localhost:8081';

$hi = return_sumfink('scalar');
print $hi . "\n";

The sub return_sumfink never gets called. Where am I wrong? Is there good reading material about SOAP somewhere out there?

Any hint is appreciated,
TIA

Finally solved it, it was a problem with my package declaration. I specified "package do_something" instead of "package modules::do_something". The package entries in the symbol table were invalid, so the subs never got called.
