Environment Setup

Setting up the development environment was a breeze.
Good documentation and tutorials were freely available.

My recommendation is to go through the presentations in the developer zone.

or the tutorials atLiferayPedia

NOT RECOMMENDED to use the liferay quickstart guide as there are some little mistakes here and there that wasted a few hours of my time. The quickstart guide 4.0.0 is still RC1 as I am typing this document. RC1 is not good enough, yet.

Next step is to write a portlet...
