Although you can build Web services with other technologies, SOAP, WSDL, and UDDI have become the de facto standards for Web services. SOAP, WSDL, and
UDDI are the most widely accepted Web services technologies, and products supporting these technologies are available from dozens of vendors.
Surprisingly, though, the SOAP-related technologies were not developed by an accredited standards organization. For the most part, these technologies
were developed by IBM and Microsoft.
