This course will integrate a combination of instructor-led discussions and interactive workshops to demonstrate the capabilities of Web Service within ecommerce applications. This seminar will illustrate the building, testing and deployment of Web Services, explore their fundamental capabilities, utilization of SOAP and XML, role of WSDL (Web Services Descriptive Language), use of UDDI registries and the development of JavaBeans and EJBs as Web Services.
