First WSDL Test Failed with SOAP::Lite

∟First WSDL Test Failed with SOAP::Lite

This section provides a tutorial example on how to use the service() function to WSDL to call a Web service. Test failed with incorrect Envelope namespace.

According to SOAP::Lite 0.710 manual, WSDL is supported with the service() function. Since get GetSpeech Web service provides WSDL at http://www.xmlme.com/WSShakespeare.asmx?WSDL, I wrote my first SOAP::Lite WSDL client program like this:

#- GetSpeech_WSDL_Test.pl
#- Copyright (c) 2009 HerongYang.com. All Rights Reserved.
#- All rights reserved
#
   use SOAP::Lite +trace;
   my $result = SOAP::Lite
      ->service('http://www.xmlme.com/WSShakespeare.asmx?WSDL')
      ->readable('true')
      ->GetSpeech('To be, or not to be');

The code looks simple. But it is not working:

The error message tells me that:

The namespace for the Envelope is wrong. I need to find out why "http://schemas.xmlsoap.org/wsdl/soap/" is used as the Envelope namespace.
'Content-Type: text/xml; charset=utf-8' in the request tells me that SOAP 1.1 was used as the default.
'SOAPAction: "http://xmlme.com/WebServices/GetSpeech"' in the request was correctly generated.
'<Request xsi:type="s:string">To be, or not to be</Request>' in request was correctly generated.
