Core Web Services and SOA for J2EE Developers

  This course can be requested in your area here.

SOA and Web Services represent a groundbreaking evolution in distributed computing. The concepts are not altogether new, but the application of them, and the unanimous acceptance of core standards like HTTP, XML, SOAP, WSDL, and the various WS-* policies, has paved the way for XML Web Services and service-oriented architectures. This course explores what separates an ad hoc set of web services (NOT SOA) from a managed, vibrant, reusable catalog of enterprise services (definitely SOA), providing an overview of the entire spectrum from the promise of cloud computing to the grit of XML content. Students will gain critical hands-on experience with implementations of the Java XML and Web Service APIs including JAXP, JAXB, JAX-WS, WSEE, and XWSS. In terms of Java, the focus is on using the JAX-WS and JAXB APIs and implementations as the basic for generating and deploying web services and service clients.An overreaching concern related to services is security. Various aspects of security are woven into this course, allowing students to see the entire spectrum of issues as well as solutions. These include encryption, digital signatures, authentication and authorization assertions, and recognized application security issues such as Cross-Site Scripting and Injection attacks.
