RESTful Services, Part 1 of 5: Overview and JAX-RS

Course description

JAX-RS is the specification for RESTful web services on the JEE platform. In this course we will take a look at the basic elements of building a REST service in Java. You will learn about how JAX-RS matches URL paths to java method calls as well as the various and many annotations that are provided by the framework to build a fully functional REST service. Code along with me and let’s build some RESTful services.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This course assumes that the users have experience coding with Java.
