Programming REST Web Services with JAX-RS 1.1 - WebSphere 8.0 / RAD 8.0 Training
Courseware: Available for sale
This course covers the design principles of REST architecture along with the details of how to implement these services with JAX-RS. 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.
