Adding admin resources
First you add the bundle to your application:
public class TestApplication extends Application<TestConfiguration> {
    private final AdminResourceBundle adminResource = new AdminResourceBundle();
    @Override
    public void initialize(final Bootstrap<TestConfiguration> bootstrap) {
        bootstrap.addBundle(this.adminResource);
    }
    @Override
    public void run(final TestConfiguration configuration, final Environment environment)
            throws Exception {
        final JerseyEnvironment adminJerseyEnvironment = this.adminResourceBundle
                .getJerseyEnvironment();
        // Not necessary, but with this you can make sure you use the same settings
        // of your jackson mapper settings for both jersey environments.
        adminJerseyEnvironment.register(new JacksonBinder(environment.getObjectMapper()));
        adminJerseyEnvironment.register(new TestResource());
    }
} 
The following will show on your logs when the admin resource is successfully registered:
