You Will Learn How To

  • Develop, deploy and monitor Web services and Web service clients with JAX-WS
  • Implement a Service-Oriented Architecture (SOA) using Web services
  • Create and deploy WSDL-first and code-first Web services
  • Build synchronous and asynchronous Web service clients in Java
  • Deliver RESTful Web services for server-side AJAX
  • Secure Web services programmatically and declaratively

Course Benefits

Web services revolutionize the way businesses interact by enabling interoperability between applications on different hardware and software platforms. The Java APIs for XML Web Services (JAX-WS) deliver a set of powerful tools to develop a Service-Oriented Architecture (SOA). This hands-on course provides the skills to design and build Web services using Java. You develop services and clients using the latest standards-based technologies. You also deploy secure Web services that integrate proven security strategies.

Who Should Attend

Programmers, architects, managers and those interested in integrating applications over the Web. Course 471, "Java Programming Comprehensive Introduction," or equivalent knowledge is assumed.
