Play Framework
The Play Framework is a java based web programming system, that includes the enterprise features of java with the methodology of Ruby on Rails or Django. You can view an introductory screencast at their website which shows just how easy and powerful it is.

Allow your user to sudo
Since this blog is aggregated on many Ubuntu sites, we will use the sudo facility to run commands instead of root. To enable sudo the same way Ubuntu does:

1. su – # Get root
2. visudo
3. Uncomment the line “%wheel ALL=(ALL) SETENV: ALL”

Install packages
For the play framework the launch scripts are in python. Zsh is installed for a better shell, and vim is installed for a full featured editor.

export PKG_PATH=ftp://ftp.openbsd.org/pub/OpenBSD/4.6/packages/i386/
sudo pkg_add zsh jre-1.7.0.00b59p0 wget python-2.6.2p0 vim-7.2.190p1-no_x11 unzip
sudo ln -sf /usr/local/bin/python2.6 /usr/bin/python
sudo ln -sf /usr/local/bin/python2.6-config /usr/bin/python-config
sudo ln -sf /usr/local/bin/pydoc2.6  /usr/bin/pydoc

Install Play Framework

cd /usr/local
sudo wget http://download.playframework.org/releases/play-1.0.zip
sudo unzip play-1.0.zip

Start your project

cd /var
sudo /usr/local/play-1.0/play new ourappname
sudo chown -R ourusername ourappname
cd ourappname
# Set java home -- you can set this permanently in /etc/login.conf or in a startup script
export JAVA_HOME="/usr/local/jre-1.7.0/"
/usr/local/play-1.0/play run

Done
Your test app is now listening on port 9000 of the systems IP. That is all there is to it. Make sure to check out the excellent documentation available for the Play Framework.
