Web Service Components
The main web service components are as follows:
- SOAP
- WSDL
- UDDI
SOAP
SOAP is an acronym for Simple Object Access Protocol. It is an XML-based protocol for accessing web services and a W3C recommendation for communication between applications. SOAP is platform and language-independent. In other words, it can be used with Java, .Net, or PHP on any platform.
WSDL
WSDL is an acronym for Web Services Description Language. WSDL is an XML document containing information about web services, such as the method name and parameter and how to access them. WSDL is a part of UDDI. It acts as an interface between web service applications.
UDDI
UDDI is an acronym for Universal Description, Discovery, and Integration. UDDI is an XML-based framework for describing, discovering, and integrating web services. UDDI is a directory of web service interfaces described by WSDL, containing information about web services.
