RESTful Web Services with Java
Training duration: 8 academic hours (1 day)
Target audience: The course targets programmers that will be implementing RESTful web services with Java.
Prerequisites: The participant should have a good command of Java-language and basic understanding of JavaEE-environment.
Contents of this training
The RESTful services are conquering the world; nearly all solutions use RESTful interfaces to some extent. RESTful services can be used for client-server communications where the client very often is either web- or mobile application, but they can equally be used in system integration scenarios.
Regardless of technology the basic implementation of the service is often rather straightforward and simple. The services are built on top of HTTP-protocol and good understanding of HTTP is required for good implementation of service interface. There are also quite a few design considerations that should be taken into account before jumping into coding of RESTful interface.
