Once you have the appropriate dependency set up, the next step is to enable the declarative linking feature by registering the org.glassfish.jersey.linking.DeclarativeLinkingFeature class with the application. You can do this via the org.glassfish.jersey.server.ResourceConfig class, as shown in the following code snippet:

//Other imports are omitted for brevity 
import org.glassfish.jersey.server.ResourceConfig; 
import org.glassfish.jersey.linking.DeclarativeLinkingFeature;  
@Provider 
@javax.ws.rs.ApplicationPath("webresources") 
public class ApplicationConfig extends ResourceConfig { 
  public ApplicationConfig() { 
    // Register a class of JAX-RS component 
    register(DeclarativeLinkingFeature.class); 
    //Package that needs to be scanned for other resource 
    packages("com.packtpub.rest.ch5.service"); 
  } 
}
