Kursbeskrivning: REST Service Development with Java

This 3-day instructor-led 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.

Students should have:

• Practical knowledge of the Java programming language, which can be gained through experience or by successfully completing one of the Java SE 5 Programming Fundamentals courses (WD152SE) (VD152) or (ZD152SE)
• Knowledge of 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. This knowledge can be gained by attending one of the following courses:

• Mastering Servlet and JSP Development with Rational Application Developer V7.5 (RD810SE) or (WD510)
• Java EE 5 Development for WebSphere Application Server V7 (WD370SE) or (VD370)
