2-Days Instructor-led

Learn the core concepts, principles, and Java implementations for RESTful services.

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.
