Oracle Workshop for WebLogic: Create WSDL (Web Service Definition Language)

WSDL Definition anf Overview

WSDL (Source: en.wikipedia.org)

WSDL (Web Service Definition Language) is an important part of Web Service. WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information [W3 definition of WSDL]. In the simple term, Web Services Description Language is an XML-based language that is used for describing the functionality offered by a Web service [WikiPedia definition of WSDL]. WSDL is a document written in XML which describes a Web service, specifies the location of the service and the operations (or methods) the service exposes [W3 School definition of WSDL].

WSDL files are used as an information communication interface between web service providers and consumers. A WSDL description which contains input and output specifications allows a client to utilize a web service’s capabilities without know implementation details and complex process of the web service.
