Programmatically configuring JAX-RS resources during deployment

The JAX-RS supports multiple ways to configure a RESTful web service application. A common approach is to subclass javax.ws.rs.core.Application and configure RESTful resources by overriding the appropriate methods. To learn more about configuring JAX-RS applications, refer to the Packaging and deploying JAX-RS applications section in Appendix, Useful Features and Techniques, of this book.

The Jersey framework provides more advanced configuration options for JAX-RS applications through the org.glassfish.jersey.server.ResourceConfig class. The ResourceConfig class is subclassed from javax.ws.rs.core.Application. We have used the Application class in the previous chapter for configuring a vanilla JAX-RS application. The ResourceConfig class offers many extra configuration features on top of the standard JAX-RS Application class.
