Základní info
In this course, students learn about the role of Web services in service-oriented architectures (SOA) and the enterprise, in addition to the technologies that are typically used in Web services. Students start by learning about the components of Web Services Description Language (WSDL) documents and SOAP messages in Web services. Students then learn how to use IBM Rational Application Developer V7.5 to create Web services using the Web service wizards, how to debug and monitor Web services using the TCP/IP monitor, and how to configure policies for Web service management. The course also covers how to package and deploy Java EE 5 Web services to IBM WebSphere Application Server V7, how to work with attachments in Web services, and how to create asynchronous Web service.
In addition, this course teaches students about the qualities of service for Web services. For example, students learn how to use the Web Services Interoperability (WS-I) features to develop Web services that are interoperable with other platforms such as Microsoft .NET. Students also learn about Web service caching for performance optimization and the WebSphere Application Server Web service security model.
Throughout the course, students perform hands-on exercises that build their practical knowledge working with Rational Application Developer V7.5 and WebSphere Application Server V7 to build, deploy, debug, and monitor Web services. Skills covered in the exercises include generating Web services from existing JavaBeans, creating and managing Web service clients, implementing security, and enhancing performance through caching, These hands-on exercises enable students to use a powerful, integrated Web service development environment within Rational Application Developer V7.5 so they can build enterprise-strength service-oriented architectures within the enterprise.
