Play Framework

Over the next few weeks I’ll be doing a few presentations about Java, Scala, Play Framework 2, HTML5, and Heroku:

• Wednesday April 11 @ 11:30am - Emerging Technologies for the Enterprise (Philedephia, PA) - HTML5 Apps in Java & Scala with the Play Framework

• Wednesday April 18 @ 13:30 - Devoxx (Paris, France) - Developing, Deploying and Scaling in the Cloud with Play

• Thursday April 19 @ 14:30 - Devoxx (Paris, France) - Client/Server Apps with HTML5 and Java

This week I’ll will be doing a few presentations about running Java and Play apps on Heroku:

• Portsmouth, NH on Tuesday March 20 @ 6:30pm - Running Java, Play! and Scala Apps on the Cloud
• DevNexus in Atlanta, GA on Wednesday March 21 @ 2:30pm - Introduction to Heroku
• DevNexus in Atlanta, GA on Thursday March 22 @ 2:30pm - Intro to Play Framework

Hope to see you there!

Play Framework 2 RC2 has been released and it is quickly becoming a mature and productive way to build modern web apps. Lets walk through building a quick app with Play 2, Scala, Anorm, JSON, CoffeeScript, and jQuery. Once the app works locally we will deploy it on the cloud with Heroku. (Note: This is the Play 2 + Scala version of my Play 1 + Java tutorial.) You can grab the completed source from GitHub.

My Java User Group Tour continues this week in Seattle, Gainesville, and Orlando. I’ll be presenting about how to run Java, Play Framework, and Scala apps on the Cloud. Check out the JUG sites for details:

• Tuesday February 21 in Seattle
• Wednesday February 22 at the Gator JUG
• Thursday February 23 in Orlando

Hope to see you there!

If you haven’t been able to make it to one of my Java User Group talks about Heroku but you want to see the presentation, then you are in luck! The Portland JUG recorded my talk on Running Java, Play Framework, and Scala Apps on the Cloud with Heroku. Check it out and let me know if you have any questions or comments. Thanks!

In just a few weeks I’ll be over in Europe presenting about Heroku at two fantastic Java conferences. First up is Jfokus in Stockholm! On February 14 at 20:00 I will be leading a Cloud Conversations BoF. Then on February 15 at 11:10 I will be speaking about how to “git push” Java & Play! Apps to the Cloud. This will be my first time speaking at Jfokus and I’m really excited because I’ve heard such great things.

I just published a [Heroku Plugin for Play Framework][1]. Right now it just deploys a Play app to Heroku. Try it out:

1. [Signup for a Heroku account][2]
2. Install the Heroku plugin locally: ```bash $ play install heroku

  3. Create a Play (1.2.3 or 1.2.4) app: ```bash
$ play new foo --with heroku

Or if you already have an existing Play app, add the follow line to the _conf/dependencies.yml_ file and then run "play deps -sync":

```yaml

• play -> heroku 0.2

  4. Deploy the app: ```bash
$ play heroku:deploy foo

You should see something like:

```bash

~ _ _ ~ _ __ | | __ _ _ | | ~ | ‘ | |/ ’ | || || ~ | /||_|__ () ~ || |__/

Over the next few days I’ll be presenting about Java, Play Framework, and Scala on Heroku at a couple Java User Groups and a MongoDB conference:

• Cincinnati JUG on January 26th
• Detroit JUG on January 31st
• MongoDB Boulder on Febuary 1st

Hope to see you there!

I’ve just posted the first release of the S3Blobs Play Framework Module. This module makes it easy to upload and download files from Amazon S3 from a JPA entity in a Play Framework Java application. This module is based on a POC that I did a few months ago, the JPA stuff from Tim Kral, and the modularization done by Roderik van der Veer. For more details on how to use the module check out the documentation, my tutorial (slightly out of date now), and the source code. This makes it really easy to save file uploads to an external system when running Play! apps on Heroku. Let me know if you have any questions. Thanks!

This week I’ll presenting at three Java User Groups about Running Java, Play! and Scala Apps on the Cloud:

• San Diego Java User’s Group on Tuesday, January 17th
• Silicon Valley Web JUG on Wednesday, January 18th
• The Capital District Java Developers Network on Thursday January 19th

Hope to see you there!
