In Complete Java RESTful Services, students not only learn the concepts and design principles associated with Representational State Transfer (REST), they also take a deep dive into JAX-RS – Java’s standard API for REST development.  This is an intense hands-on course for Java programmers intent on learning how to design and build RESTful services and clients that exchange information in plain text, XML, JSON and other formats.  Students spend almost 50% of their time in labs building JAX-RS services and REST clients.
