Service Code:

package com.naresh.resteasy;

import javax.ws.rs.GET;
import javax.ws.rs.Produces;
import javax.ws.rs.Consumes;
import javax.ws.rs.Path;

@Path("/HelloResteasy")
@Produces("text/plain")
@Consumes("text/plain")
public class HelloService {

    @GET
    @Path("/response")
    public String printResponse(){
        return "Hello";

    }

}

Code for Service Class Implementation

package com.naresh.resteasy;

import java.util.HashSet;
import java.util.Set;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

-------------------------
@ApplicationPath("/service")
public class HelloApplication extends Application {

    private Set<Object> singletons = new HashSet<Object>();

    public HelloApplication() {
        singletons.add(new HelloService());
    }

    @Override
    public Set<Object> getSingletons() {
        return singletons;
    }

}

The value of the @Path annotation is a case-sensitive string. In your service code, HelloService is annotated with @Path("/HelloResteasy"), but your request path is http://localhost:8080/RestEasyHello/service/HelloRestEasy/response/

The @ApplicationPath defines the relative base URL path for all JAX-RS services in the deployment. So, in your code, all of JAX-RS RESTful services should be prefixed with the /services path when you execute. That is, http://localhost:8080/service/HelloRestEasy/response/
