  • Overview

    This course provides in-depth coverage of REST principles and building RESTful services using the JAX-RS 2.0 API. It includes a brief overview of SOAP-based services and WSDL, to provide a contrast to RESTful services. You will emerge from the course with a full understanding of the HTTP protocol and its vision of the “original web,” and how these ideas are implemented in RESTful applications. We’ll show you how to handle the most common types of request input, culminating in the transmission of HTTP entities in both XML and JSON format, in line with the original intention of HTTP. You’ll also learn how to create appropriate responses given a variety of inputs and conditions, according to the guidelines and principles in the HTTP standard.
