Yes, it's possible. Perhaps you would like to know how? :)

Here's a "quick-n-dirty" example:

import org.jboss.resteasy.annotations.providers.jaxb.Formatted;
import org.jboss.resteasy.annotations.providers.jaxb.Wrapped;
import org.jboss.resteasy.core.Dispatcher;
import org.jboss.resteasy.core.ResourceInvoker;
import org.jboss.resteasy.core.ResourceMethod;
import org.jboss.resteasy.core.ResourceMethodRegistry;
import org.jboss.resteasy.mock.MockDispatcherFactory;
import org.jboss.resteasy.mock.MockHttpRequest;
import org.jboss.resteasy.mock.MockHttpResponse;
import org.junit.Test;

import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlValue;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Set;

public class PrintAllResourcesTest {

    @Test
    public void name_StateUnderTest_ExpectedBehavior() throws Exception {
        Dispatcher dispatcher = MockDispatcherFactory.createDispatcher();

        dispatcher.getRegistry().addSingletonResource(new MetaService());
        dispatcher.getRegistry().addSingletonResource(new Service());

        MockHttpResponse response = new MockHttpResponse();
        MockHttpRequest request = MockHttpRequest.get("/meta")
                .accept(MediaType.APPLICATION_XML);


        dispatcher.invoke(request, response);

         /*
         
            /service/
            /service/
         */
        String result = response.getContentAsString();
    }

    @XmlRootElement(name = "resource")
    public static final class JaxRsResource {
        @XmlAttribute String method;
        @XmlValue String uri;

        public JaxRsResource() {}

        public JaxRsResource(String method, String uri) {
            this.method = method;
            this.uri = uri;
        }

        @Override
        public boolean equals(Object o) {
            if (this == o) return true;
            if (o == null || getClass() != o.getClass()) return false;

            JaxRsResource that = (JaxRsResource) o;

            if (method != null ? !method.equals(that.method) : that.method != null) return false;
            if (uri != null ? !uri.equals(that.uri) : that.uri != null) return false;

            return true;
        }

        @Override
        public int hashCode() {
            int result = method != null ? method.hashCode() : 0;
            result = 31 * result + (uri != null ? uri.hashCode() : 0);
            return result;
        }
    }

    @Path("/service")
    public static final class Service {

        @GET
        @Path("/")
        public String getStuff(){
            return "";
        }


        @POST
        @Path("/")
        public String postStuff(){
            return "";
        }
    }


    @Path("/meta")
    public static final class MetaService {
        @Context Dispatcher dispatcher;

        @GET
        @Path("/")
        @Wrapped(element = "resources")
        @Formatted
        public Set getAllResources(){
            Set resources = new HashSet();

            ResourceMethodRegistry registry = (ResourceMethodRegistry) dispatcher.getRegistry();

            for (Map.Entry> entry : registry.getRoot().getBounded().entrySet()) {
                for (ResourceInvoker invoker : entry.getValue()) {
                    ResourceMethod method = (ResourceMethod) invoker;

                    if(method.getMethod().getDeclaringClass() == getClass()){
                        continue;
                    }

                    for (String verb : method.getHttpMethods()) {
                        String uri = entry.getKey();
                        resources.add(new JaxRsResource(verb, uri));
                    }
                }
            }

            return resources;
        }

    }
