JBoss Training: Programming REST Web Services with JAX-RS 2.0 - Wildfly / JBoss Developer Studio Training

This JAX-RS 2.0 training course covers the design principles of REST architecture along with the details of how to implement these services with JAX-RS 2.0. This will allow students who take the course to implement RESTful services using Java standards that will be portable to many different Java environments. Although many of the services in active use are SOAP or at least XML-based, an increasing number of services take a RESTful approach to data transmission. Representational state transfer (REST) is a style of software architecture that differs from the more traditional Remote Procedure Call (RPC) style of data transmission, instead emphasizing the importance of defining and retrieving representations of resources. This course uses the Wildfly server and Eclipse.  Wildfly is the open source project for the JBoss Enterprise Application Platform and was renamed from JBoss Application Server (JBoss AS) for this version. Wildfly 8 supports Java EE 7 and JAX-RS 2.0, the version covered in this course.
