Play Framework

This week I’m starting a Java User Group tour where I’ll be travelling to JUGs around the US (or maybe world). On the tour I’ll be giving a talk about Running Java, Play! and Scala Apps on the Cloud. Here is the description:

Heroku is a Polyglot Cloud Application Platform that makes it easy to deploy Java, Play! and Scala apps on the cloud. Deployment is as simple as doing a “git push”. This session will teach you how to instantly deploy and scale Java, Play! and Scala apps on Heroku.

UPDATE: I’ve released a S3 Play Module based on this project.

A couple of questions [1, 2] on StackOverflow.com led me to look into how we can send file uploads in a Play Framework application to Amazon S3 instead of the local disk. For applications running on Heroku this is especially important because the local disk is not persistent. Persistent disk storage makes it hard to scale apps. Instead of using the file system, it’s better to use an external service which is independent of the web tier.

Next week I am speaking in Oslo at JavaZone about deploying Java and Play! Framework apps on the Cloud. I submitted the session before Heroku for Java was available so I had to obfuscate the title and description. If you are at JavaZone then I hope to see you at my “Deploying Apps on Heroku” session!

UPDATE: This tutorial is for Play 1.x (an old version). Check out my Play 2 Tutorial if you want to get started with the latest stuff.

Last week Heroku announced that you can now run Java apps on Heroku. Today Heroku announced that you can also easily run Play Framework apps on Heroku! Here’s a quick guide to getting started with Play! on Heroku:

1. Install the heroku command line client on Linux, Mac, or Windows.

UPDATE: This is only for Play 1.x with Scala. Getting Play 2 projects (Java or Scala) working in IDEA is now as easy running “play idea” and then opening the project.

Update 2: I’ve posted a new video showing how to create and run Play2 apps in IntelliJ.

Yesterday at the [Programming Summer Camp][1] a group of us were working together to learn the [Play Framework][2]. Once we were able to get the basics working we wanted to get everything working in [IntelliJ IDEA][3]. Due to a lack of good documentation on the subject things did not go smoothly until we figured out the right “magical incantations”. We did eventually get it working so I wanted to document the steps we took.
