Web Service Components

1. SOAP (Simple Object Access Protocol) - XML based
2. WSDL (Web Service Description Language) - WSDL is a xml document containing information about web services such as method name, method parameter and how to access it.
3. UDDI (Universal Description, Discovery and Integration) - UDDI is a directory of web service interfaces described by WSDL, containing information about web services.

SOAP Web Service

•  It is platform independent and language independent
• SOAP uses WSDL and doesn't have any other mechanism to discover the service.

RESTful Web Service
