MessageApplication.java

 package uz.salvadore.rest;

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

 @Path("/message")
 @Produces("text/plain")
 public class MessageRestService {

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

 }     

我使用tomcat 7.0.69
我的错误http://localhost:9999/RESTEasy/rest/message/hello
