Web service technology promises to provide a ynamic integration and interaction of heterogeneous systems, thereby to facilitate fast and efficient cooperation among the entities in cooperative environments. With the surge of Service Oriented Architecture (SOA) and Web Services, service discovery has become increasingly crucial. Web service discovery mechanism retrieves relevant web services from the internet to serve a wide range of users such as service consumers, service developers, service deployers, and service brokers. This paper demonstrates the model for discovery of web services using WSDL processing system and comparison between WSDL(Web Service Description Language) and UDDI(Universal Description Discovery and Integration) based discovery system. The solution leverages WSDL retrieval according to the requested term using horizontal and vertical search and processing WSDL to find suitable web services to satisfy the user request during run time.
