This talk covers technology aspects of SOAP protocol and shows how to use Perl to build SOAP client and server implementations in portable, platform independent fashion in a minutes. Based on SOAP::Lite module available from CPAN or from soaplite.com.

Techniques covered include:

• XML serialization, rules and limitations
• SOAP clients: implement RPC and OO calls
• Access to services on Internet
• SOAP servers, different implementations: CGI, mod_perl, Apache::Registry, daemon. Installation and configuration
• Adding SOAP interfaces for existent modules and classes
• Security: SSL and authentication
• Diagnostics and error recovery: error handling and debugging
• Service descriptions: access with service description (WSDL), stub generation
• SOAP clients and servers with COM/DCOM interfaces: easy SOAP calls from VB or VBA. Minimum installation and configuration
• Service repository (UDDI): inquiry and publishing interfaces
• SOAP one-liners in Perl and VB
• CPAN: how to leverage it and don't reinvent the wheel
