And i get a 404 Not Found

There is the class:

package com.trofimovep;



import javax.enterprise.context.ApplicationScoped;

import javax.ws.rs.GET;

import javax.ws.rs.Path;

import javax.ws.rs.core.Application;

import javax.ws.rs.core.Response;



@ApplicationScoped

@Path("/he")

public class Start extends Application {

    @GET

    @Path("/books")

    public Response showBooks() {

        String output = "This is a BookShop !";

        return Response.status(200).entity(output).build();

    }

}

I try almost variants: created another class which extends from Application, remove the @ApplicationScoped,
and all my actions don't give the result, it is 404 NOT FOUND on http://localhost:8080/he/books.
What i do wrong? Why it can not see the message by path?

I dont see you using this in your URL

<context-root>/Bookapp</context-root>

so maybe bookapp/he/books would work

It should to create empty class extends Application for saying that it's JAX-RS application

import javax.enterprise.context.ApplicationScoped;

import javax.ws.rs.ApplicationPath;

import javax.ws.rs.core.Application;



@ApplicationScoped

@ApplicationPath("")

class Rest extends Application {

    public Rest() {

    }

}
