Mastering SOA  Java Web Services


Mastering SOA and JEE Web Services focuses on providing an understanding of the fundamental technologies used in web services. This understanding is critical to being able to diagnose, troubleshoot, tune, and perform other lifecycle activities. Students will leave the course armed with the required skills to design, implement, test, and support JEE web services.

This lab-intensive course provides students with hands-on experience with implementations of the Java XML and Web Service APIs including JAXP, JAXB, JAX-WS, JAX-RS, WSEE, and XWSS. In terms of Java, the focus is on using the JAX-WS, JAX-RS, and JAXB APIs and implementations as the basic for generating and deploying web services and service clients. 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. An overreaching concern related to services is security.

Course Key Learning Summary
