Each section starts with the simpler features and ends with more advanced Grails features. The book is intended to browse through the subjects. You should be able to just open the book at a random page and learn more about Grails. Maybe pick it up once in a while and learn a bit more about known and lesser known features of Grails.

About the Author

Hubert Klein Ikkink
Hubert A. Klein Ikkink (mrhaki)

Hello. I am a passionate Groovy, Grails and Java developer based in Tilburg, The Netherlands. My goal is to write software, like Pixar makes movies, BMW makes cars, Bang & Olufsen makes audio and TV systems and Apple makes computers and devices: clean, elegant, user-centered and high quality.

My name is Hubert A. Klein Ikkink. Not a very common name, right? To make things easier I just picked the first letters of my firstname and surname and came up with haki. So there you have it, now I am known as Mr. Haki or mrhaki for short.

In 2009 I started writing blog posts about Grails with the name Grails Goodness. These posts contain small snippets of code explaining core and exotic features of the Grails platform.
