Introduction to Java Web Services Using Oracle JDeveloper

Course Number: JK
Recommended Duration: 2-3 Days

Intended Audience: Experienced Java programmers needing to learn how to create and use Web Services.

Course Overview

Service Oriented Architecture (SOA) is a standards-based architecture where business processes are represented by one-or-more independent services that may be orchestrated into new applications as needed. Services are represented by one-or-more software components. Today Web Services provide the backbone components of SOA for most organizations. This course introduces the core concepts of SOA and Web Services. Participants will learn to use Oracle JDeveloper and Java to use existing Web Services and to create Web Services for others to use. Class exercises will create and use both SOAP and REST Web Services.
