Unsupported Media Type: "application/soap"

This section provides a tutorial example showing the Unsupported Media Type 'application/soap' error, when using SOAP::Lite with soapversion('1.2').

Based on the result of my last tutorial, I think I am ready to try my SOAP 1.2 client application with the real server at xmlme.com:

#- GetSpeech_SOAP_1_2_Test.pl
#- Copyright (c) 2009 HerongYang.com, All Rights Reserved.
#- All rights reserved
#
   use SOAP::Lite +trace;
   my $client = SOAP::Lite->new()
      ->soapversion('1.2')
      ->envprefix('soap12')
      ->default_ns('http://xmlme.com/WebServices')
      ->on_action( sub {join '/', @_} )
      ->readable(true)
      ->proxy('http://www.xmlme.com/WSShakespeare.asmx');

   my $som = $client->call('GetSpeech', 
      SOAP::Data->name("Request")
      ->value("To be, or not to be")
   );

Result of GetSpeech_SOAP_1_2_Test.pl:

POST http://www.xmlme.com/WSShakespeare.asmx HTTP/1.1
Accept: text/xml
Accept: multipart/*
Accept: application/soap
Content-Length: 606
Content-Type: application/soap; charset=utf-8
SOAPAction: http://xmlme.com/WebServices/GetSpeech

<?xml version="1.0" encoding="UTF-8"?>
<soap12:Envelope
    xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"

    xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">

    <GetSpeech xmlns="http://xmlme.com/WebServices">
      <Request xsi:type="xsd:string">To be, or not to be</Request>
    </GetSpeech>
  </soap12:Body>
</soap12:Envelope>
...
HTTP/1.1 415 Unsupported Media Type
Cache-Control: private
Connection: close
...

The result is disappointing, but somewhat expected. I kind of ignored the issue at the Content-Type header line. SOAP 1.2 requires to use the "application/soap+xml" media type, not "application/soap".
