Developing RESTful Web Services in Java Course

Course Summary

The Developing RESTful Web Services in Java training course is designed to demonstrate an in-depth examination of how to build Representational State Transfer (REST)ful web services using the Java Application Programming Interface (API) for RESTful Web Services, or JAX-RS.

The course begins with an overview of web services development in the Jakarta Enterprise Edition (EE) platform, and then moves into creating web services using the JAX-RS API. Next, it analyzes the advantages and disadvantages of REST. The class concludes with learning how to use common Java related APIs to build web services, including Java Architecture for XML Binding (JAXB), JAX-RS, client JAX-RS, and JavaScript Object Notation (JSON).

Prerequisites: A familiarity with general web services concepts, Extensible Markup Language (XML), and have a proficient command of the Java and Jakarta EE platforms.

Purpose
