SOAP::Lite for Perl is a collection of Perl modules which provides a simple and lightweight interface to the Simple Object Access Protocol (SOAP, also known as Service Oriented Access Protocol) both on client and server side.
In my work going through the SOAP::Lite code base fixing bugs and what not, I ran across an old email thread on the newsgroup asking about a fault that their client kept receiving from a SOAP Server written in Perl:
Failed to access class (Majordojo:TemperatureService):
syntax error at (eval 123) line 1, near "require Majordojo:"
The root of the problem stems from the fact that the SOAP Action header, and/or the namespace of the method being invoked uses a URI format that confuses SOAP::Lite. In this case the URI is urn:Majordojo:TemperatureService. SOAP::Lite is not crazy about this format because when it tries to import the module Majordojo:TemperatureService it fails because it is not a valid module name. The call was failing because the server written in Perl was using SOAP::Lite default dispatch methodology, or the simplistic dispatch-to() subroutine.
