In this lab-intensive course, you will cover the entire spectrum of technologies that enable web services in Java and JEE. This course focuses on what separates an ad hoc set of web services (NOT SOA) from a managed, vibrant, reusable catalog of enterprise services (definitely SOA). You will gain practical, hands-on experience with implementations of the Java XML and Web Service APIs including JAXP, JAXB, JAX-WS 2.0, WSEE, and XWSS. In terms of Java, you will focus on using the JAX-WS 2.0 and JAXB APIs implementations as the basis for generating and deploying web services and service clients.

What You'll Learn

• Apply the basic concepts of Service-Oriented Architecture (SOA) to the identification and design of web services
