How to create custom “Action Not Found” page on Play Framework 2.4 (Java)

[Satomi Moriki]

Currently, if I access to non-defined path on my play framework application, default "Action Not Found page" appears. 

I tried to make custom "Action Not Found page" in order not to show system information on browser.

I checked the page.

https://www.playframework.com/documentation/2.4.x/JavaErrorHandling

And I implemented the following code.

package controllers;

import play.Logger;
import play.http.HttpErrorHandler;
import play.mvc.*;
import play.mvc.Http.*;
import play.libs.F.*;
import views.html.*;

public class ErrorHandler implements HttpErrorHandler {
    public Promise<Result> onClientError(RequestHeader request, int statusCode, String message) {
        Logger.debug("onClientError");
        return Promise.<Result> pure(
                Results.badRequest(error.render())
        );
    }

    public Promise<Result> onServerError(RequestHeader request, Throwable exception) {
        Logger.debug("onServerError");
        return Promise.<Result> pure(
                Results.internalServerError("A server error occurred: " + exception.getMessage())
        );
    }
}

However error.scala.html isn't shown and default "Action Not Found page" appears. 

Logger.debug also wasn't called.

I found same question for Scala, but there isn't any answer.

I forgot to put version : [2.4-java]

I solved this problem by myself! I noticed that I should add ErrorHandler.java to default package or add to another package and write its class path to application.conf like this.

play.http.errorHandler = "com.example.ErrorHandler"

Thank you for your support!

I'm trying the same thing and I've the same problem. But for default package do you mean the controllers package?
I've put the ErrorHandler.java in the controllers package without modify the application.conf, is it correct?
