Service class

package itsvenkis.blogspot.in.resteasy.examples;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;

@Path("/helloworld")
public class HelloWorldService {

    @GET
    @Path("/{param}")
    public Response greetUser(@PathParam("param") String name) {
        return Response.status(200).entity("Hello World " + name).build();
    }
}
 

Now build and deploy the war file and start your server and try this url http://localhost:8080/resteasyTutorials/resteasy/helloworld/nandu
