Play-Rest API with Java - basic response

Question

I'm new in the server-side , and I'm trying to learn how to use play in rest api with java and restangular. I made a project for java in the intellij. I want the GET request to return an html page and not html.scala page. how do I change this function that it will return the app/views/index.html instead the app/views/index.html.scala

also if someone have a good website to learn from, it will help a lot

the function in java :

package controllers;

import play.*;
import play.mvc.*;

import views.html.*;

public class Application extends Controller {

    public static Result index() {
        return ok(index.render("Your new application is ready."));
    }

}

the routes page :

# Routes
# This file defines all application routes (Higher priority routes first)
# ~~~~

# Home page
GET     /                           controllers.Application.index

# Map static resources from the /public folder to the /assets URL path
GET     /assets/*file               controllers.Assets.at(path="/public", file)

Answer 1

I found a similar question with good answer with a lot of examples. you can find it here. The easiest way is to make a GET request for the / and to send the destination also, like this:

# Home page
GET     /                           controllers.Assets.at(path="/public",file="index.html")
