Deploying a Play! app to Azure via Jenkins
Here at Wanari, we use Play Framework for many of our projects and maintain products on our own servers. Not too long ago, a client of ours requested to move such product to Azure Cloud.

Play Framework WebSocket in Java

A Crash Course on YAML
This post will tell you how we use a simple YAML file to insert the initial data (like roles, privileges, admin user, and all the other necessary data) into our database. We use Play! Framework (Java) with Hibernate. The important part is how we make Objects from the YAML description using SnakeYAML (Play framework’s integrated YAML parser) though. I’ll give you some tricks on how to use YAML easily in order to create the initial data for your application.
I was working on a Play! Framework project and I was wondering why our whole API was available in one piece.

Subject, Role, Privilege – DeadBolt in Play! Framework
If you have a website on which users can register and login, then you also want to protect your application from attackers. We recommend you to protect your application’s actions not only from attackers, but from users, too. For example, if you want to make a user who can upload Excel files on a specific UI, then that user should neither see other UIs, nor should s/he be allowed to take any other actions.
Play framework modularization: everything you wish you had been told

In Play framework the modules are small functionality packages. These...
Deploying Your Play! Framework App to Azure as a PaaS
We wanted to deploy a Play! framework application to the cloud but we didn’t want to take care of all security updates on a virtual machine. Heroku is very expensive and Amazon has had no suitable solutions for our needs. We decided to go with Windows Azure.
