Add-on is not responding. Wait or cancel?

Hello !

I am trying to make a simple HelloWorld add-on using atlassian-connect-play-java :

My Controller : 

package controllers;
import views.html.*;
import play.mvc.Controller;
import play.mvc.Result;
public class Application extends Controller {
     public static Result index()
        return AcController.index(home(), descriptor());
     private static Supplier<Result> descriptor()
        return new Supplier<Result>()
            public Result get()
                return AcController.descriptor();
    private static Supplier<Result> home()
        return new Supplier<Result>()
            public Result get()
                return ok(index.render("Hello"));


My routes file : 

GET / controllers.Application.index()
GET /assets/*file"/public", file)
-> / ac.Routes


My index:scala.html file :

@(message: String)
@main("Welcome to Play") {


My main.scala.html file :

@(title: String)(content: Html)
<!DOCTYPE html>
        <script src="http://localhost:1990/confluence/atlassian-connect/all.js" type="text/javascript"></script>
        <link rel="stylesheet" href="//" media="all">
        <link rel="stylesheet" media="screen" href=""stylesheets/main.css")">
        <link rel="shortcut icon" type="image/png" href=""images/favicon.png")">
        <script src=""javascripts/jquery-1.9.0.min.js")" type="text/javascript"></script>
        <div class="ac-content">


My atlassian-connect.json file : 

     "key": "${addonKey}",
     "name": "${addonName}",
     "description": "Atlassian Connect add-on",
     "baseUrl": "${localBaseUrl}",
     "vendor": {
        "name": "Atlassian",
        "url": ""
     "authentication": {
         "type": "none"
     "modules": {
    "generalPages": [
        "url": "/",
        "key": "test-application",
        "location": "system.user",
        "name": {
          "value": "Test"
  "scopes": ["READ"]


What I get when I run my play application :

What I get when I install my plugin on a local instance of Confluence and run it :

I tried to find the problem but I couldn't, can someone please help ?

This will be because your addon is not responding to the iframe request for some reason.  I would suggest using firebug or google chrome developer tools to see which request is failing.  You should see a request to your addon either timing out, failing or going to the wrong host.

Thank you @Matthew Jensen, I followed your advice and I did find the request that was failing.

The url that I specified in the descriptor was invalid. A simple "/" or an empty url "" was not accepted by confluence so I had to change it to "/home" and change my routes file as well.


Thanks smile
