This section describes the operations and the support range of the Cosminexus JAX-RS engine.

The JAX-RS engine serves as the communication infrastructure of RESTful Web Services (Web resources). The operations of the engine on aWeb resource client and Web resource are as follows:

• JAX-RS engine on the Web resource client
  The JAX-RS engine receives Java objects from the Web resource client through client APIs for RESTful Web Services and generates an HTTP request. The engine sends the generated HTTP request to the called Web resource, receives an HTTP response from the Web resource, generates a Java object, and returns the generated Java object to the Web resource client.
  
• JAX-RS engine on the Web resource

The JAX-RS engine receives HTTP requests, locates the target resource class (discovery), and calls the method corresponding to the request (dispatch). When implementing discovery and dispatch, the engine executes the required injection, based on the annotation of the resource class. Also, the JAX-RS engine generates and returns HTTP responses from the target resource classes.
