REST Service Development with Java

Overview

This course teaches software developers how to build web services using Representational State Transfer (REST). Students learn the benefits of and the technical architecture for using REST in applications, including how to design, build, and test RESTful services using Java and JAX-RS. This includes the role of key technologies such as HTTP, Extensible Markup Language (XML), and JavaScript Object Notation (JSON). Students also learn how to consume RESTful services in applications, including the role of JavaScript and Ajax.

Hands-on exercises throughout the course enable students to use IBM Rational Application Developer V8 and IBM WebSphere Application Server V7 to develop a RESTful interface and servlet, debug RESTful web applications, and build a JAX-RS application.

Public

This intermediate course is designed for application developers interested in building RESTful interfaces to server-side applications in a Java EE environment.

Prerequisits

Students should have:practical knowledge of the Java programming language, and be familiar with application development in a Java Enterprise Edition (Java EE) platform such as IBM WebSphere Application Server.

Experience with Rational Application Developer or another Eclipse-based development environment is also beneficial.
