- Testing on Local Host

This section provides a tutorial example on how to generate the NumberToWords request without using the real Web service server - Letting the connection fail with a localhost proxy URL.

Based on previous experience, I know that I need to run many tests while developing the SOAP 1.2 client program to call NumberToWords at

Instead of wasting resources at, I will start my client program with a faked localhost end point to just generate the request message. So here is my first version,

#- Copyright (c) All Rights Reserved.
   use SOAP::Lite +trace;
   my $client = SOAP::Lite->new()

   my $som = $client->call('NumberToWords', 102);

When executing, it will give this output:

SOAP::Transport::HTTP::Client::send_receive: HTTP::Request=HASH(0x3034700)
   POST http://localhost/NumberConversion.wso HTTP/1.1
Accept: text/xml
Accept: multipart/*
Accept: application/soap
Content-Length: 474
Content-Type: application/soap+xml; charset=utf-8
SOAPAction: "#NumberToWords"

<?xml version="1.0" encoding="UTF-8"?>
      <c-gensym3 xsi:type="xsd:int">102</c-gensym3>

SOAP::Transport::HTTP::Client::send_receive: HTTP::Response=HASH(0x2c8efb8)
SOAP::Transport::HTTP::Client::send_receive: HTTP/1.1 404 Not Found

Not too bad. I was able to see the entire request without using a real Web service server. But:
