Unable to Run my Filter implemented with ContainerResponseFilter

I am trying to parse the GET response through a common filter and send response to the client according the content received. But I am not able to execute the Filter class. I've added the code snippet below. Any help would be appreciated

@FrontierResponse
@Provider
public class PoweredbyResponseFilter implements ContainerResponseFilter {

@Override
public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext)
        throws IOException {

    if (requestContext.getMethod().equals("GET")) {
        System.out.println("hellos");
    }

    //responseContext.getHeaders().add("X-Powered-By", "Jersey :-)");
}

}

My custom Annotation

@Target({ElementType.TYPE, ElementType.METHOD})
@Retention(value = RetentionPolicy.RUNTIME)
@NameBinding
public @interface FrontierResponse {
}

and this is my resource class

@GET
@FrontierResponse
@Produces({MediaType.TEXT_HTML, MediaType.APPLICATION_JSON})
public List<String> list() {...}

for additional information i am using

jersey jersey-bundle-1.17.jar javax.ws.rs-api-2.0.jar

You need to decorate the method of the resource class by @FrontierResponse, not the resource class. Or you may annotate extension of Application class if you want to use your filter for all requests. Check spec for more details.

EDIT: @NameBinding is in JAX-RS since v2.0. You need to use implementation o that specification, that is Jersey 2.x. In the jersey 1.x this annotation will be ignored.
