Groovy Futures

I wanted to provide a bit of history going back to Spring 2007 when I first realized that the language called Groovy and the framework called Grails had bright futures. I kept hearing about Groovy on various technical podcasts (such as The Java Posse so I started to look curious about this new language. Then I listened to a podcast by Scott Davis The Groovy Programming Language and Scott convinced me that Groovy was indeed, as it's name suggests, pretty cool.

So I began to listen to all the podcasts I could find on Groovy and Grails. The Grails Podcast provided plenty (it now has 50.) Another site that has a number of great Grails Podcasts is About Groovy. My favorite is Neal Ford's

I also began to play with Groovy and Grails. I did what everyone should do and ran the Quick Start and then a couple Tutorials.

My timing was pretty good because four books on Groovy and Grails had just become available:

Groovy in Action is my favorite. Java developers should read that book cover-to-cover. Non-Java developers need only read, initially, through chapter 6. Then read the rest of the book after they've worked with Groovy for awhile.

The Definitive Guide to Grails is just what it says. It was written by the creator of Grails. I would recommend that you read Chapter 1 and Chapter 2 of Groovy in Action before reading The Definitive Guide to Grails as the Groovy intro in the in action book is very well written.

Getting Started with Grails is tutorial based. Jason Rudolph does a very nice job. You might even read this before working your way through The Definitive Guide to Grails

Groovy Programming was written as a college text and, while thorough, it is a bit boring.

Anyway, after reading all the books and doing the various tutorials and playing with some ad hoc applications, I started to work with System i legacy database tables. And I ran into a few issues. I've resolved those issues, using the Groovy language and the Grails philosophy of "convention over configuration." I developed several tools and launched an open-source project Grails400Utils: Grails Utilities for the IBM System i

I published an article The Search for the Holy Web Development Grail(s) in the November issue of System i News. And I did my own Groovy and Grails podcast What's in a name: Groovy and Grails - The implementation, language and more

I've also developed and deployed two Grails applications that are now in production. I am currently working on three other commercial Grails applications.

The future for me is Groovy (and Grails) and I'm continuing to develop the Grails Utilities for the IBM System i while being billable doing GonG development (although I can still be coerced to do Java coding.)
