Course Description

Web services are designed to allow Web-based access to distributed software and business services. They bring a standard, open service architecture to component development that allows them to be accessed over the Web with standard protocols such as HTTP and standard XML formats for messages and service descriptions. This course will give you a thorough understanding of the current Web services architecture, and the technologies that support Web services including the new Java APIs such as JAX-WS and JSR-181. Topics include: SOAP, WSDL, JAX-WS, SAAJ, JAXB, XML, UDDI, MTOM, EJB based Web Services and the WS-* Standards. We will look at the current state of the art of Web services, what works and what doesn’t work, and also at newer standards, and how they fit into the Web services picture. This course is hands on, and students will actually build and deploy a Web service during the course
