Description
Web Services are a tool for inter-application integration and opening to the intranet, extranet or Internet, and constitute the means for developing distributed and interoperable applications. This seminar presents an in-depth study of Web Services and associated protocols: SOAP, WSDL, UDDI directory, REST, security and authentication protocol, WS-X extensions. It also shows you the main tools for creating and operating in a Java and .NET environment.
Who is this training for ?
For whom ?Project managers and developers.
