Play! in the Cloud

You’ve been waiting for it…

And now, it’s here!

We have great news for you: Jelastic now supports Play framework! Thanks to all of our active users, this great feature is now available in Jelastic PaaS. Play! is one of the most popular frameworks out there. It is written in Java and helps developer build Web application more easily with Java and Scala.

So let’s get to it. Let’s deploy your Play! application to Jelastic right now!

1. Create the environment

1. Go to and sign up if you haven’t done so yet, or log in with your Jelastic credentials by clicking the Sign In link on the page.
2. Ask Jelastic to create a new environment.

3. In the Environment Topology window, pick your application server (for example, Tomcat 6) and the database you want to use (for example MySQL). Then type your environment name, for example, framework

It will take just a minute for your environment to be created.

3. Create an application

1. Go to the and download the latest Play! framework version.

2. Unzip the package you have just downloaded.

3. Run Play framework using command line (C:play on Windows,~/play on Linux):>play

4. Install Jelastic’s module on Play:>play install jelastic

5. Once the module is successfully installed create a new application with Jelastic support:>play new jelasticapp --with=jelastic

6. Once your application is created change the application.conf file of your project (play-1.2.4jelasticappconfig). Uncomment the part of file which includes Jelastic Account configuration and change all the required strings to the following:

7. In this file, uncomment full JDBC configuration and change the database URL, driver, user and password according to your database:


8. Increase db.pool.timeout to 10000 ms in connections pool configuration of application.conf file:


9. Create your application as you usually do.

10. Deploy your application to Jelastic cloud:>play jelastic:deploy jelasticapp
That’s all you have to do. Just a few simple steps. Your app is now ready to be opened in a new browser window.

    After I type cmd to deploy :

    File Uploading : [100%]
    File Uploading : OK
    Registration project processing… : OK
    Deploy processing… : not authenticated (access denied to app [xxxxx] with session [yyyy])

    How to fix it ?

    • k0rrawit

      Ok, I can solve by myself. It cause of wrong config jelastic.api.apihoster. In your example, it’s Europe hoster but I’m use US Hoster.

      But I found new problem which I can connect to the database.

      Can’t start in PROD mode with errors

      Database error
      A database error occured : Cannot connected to the database, An attempt by a client to checkout a Connection has timed out.

      play.exceptions.DatabaseException: Cannot connected to the database, An attempt by a client to checkout a Connection has timed out.

      at play.Play.init(

    Nice work!

    One question though, will Jelastic support the Netty server (default play) in the future instead of the war packaging?

    Kind regards,


    P.S. There is a small bug in the code above: “–with=jelastic” should be “–with=jelastic”.

    Is there a way to update existing Play application for Jelastic? Could you provide a guide for it?

  4. zoitec

    What should the jelastic.api.apihoster be for the US then?

      We plan to add this feature a little later. We already have this proposed in our voting list . Please find that existing feature suggestion and vote for it. The more votes a faeture gets – the higher priority it gets in the roadmap.
