Overview

Geared for experienced developers, Java RESTful Service Essentials is a two day, lab-intensive services training course that introduces developers to the core concepts, principles, and Java implementations for RESTful services. 

Today's development environments are increasingly dominated by sophisticated tooling that makes the implementation of RESTful services less arduous.  The proper design of these services is far more complex and demanding. 

Working within an engaging, hands-on learning environment, guided by our expert team, attendees will learn to:

  • Understand and apply the basic concepts of REST
  • Understand and intelligently discuss the similarities and differences between RESTful services and SOAP-based services
  • Appreciate the security concerns associated with RESTful services
  • Design, develop and deploy real-world RESTful Services
  • Implement RESTful services using JAX-RS to
  • Handle various HTTP methods
  • Implement RESTful Java clients
  • Implement JAX-RS Filters and Interceptors
