Presentations by Jeff Brown
Agile Test Driven Development With Groovy
Dynamic languages bring a lot of interesting elements to the table for teams interested in doing Test Driven Development (TDD). Groovy lends itself very well to TDD and this session demonstrates many features of the language and its libraries that help teams build more testable systems and build better tests.Groovy And Your Build
There are numerous roles that Groovy may play in your build process to greatly simplify the management of the build while bringing more capabilities. This session will detail a lot of the things that Groovy can do to improve your build and lessen the amount of effort you spend on your build.Powerful Metaprogramming Techniques With Groovy
Metaprogramming is a key component in building truly dynamic and flexible applications with Groovy. Groovy's metaprogramming capabilities bring great new possibilities to the table that would be very difficult or just plain impossible to write with Java alone. This session will demystify a lot of the magic that seems to be going on inside of a Groovy application.A Thorough Introduction To Groovy
Groovy is an agile dynamic language for the Java platform. The language and its libraries bring many things to the table to ease the process of building applications for the Java platform. This session provides a detailed run through Groovy with lots of code samples to drive home the power of the language.Advanced Web Development With Grails
Grails makes web application development both fun and easy. This session dives beyond the basics to cover advanced details of Grails that bring the really exciting features to your applications.Extending Grails - The Plugin System
Grails is a super powerful framework for building applications for the Java platform. Grails addresses the pain points that the other web applications frameworks leave you with. This session covers the details you need to further extend Grails to help Grails help you in your environment.Grails - Agile Web 2.0 The Easy Way
Grails is a full stack MVC framework for building web applications for the Java platform. Grails makes web application development both fun and easy. This session covers all of the fundamentals of building web applications with Grails.Jeffs Groovy Web Log

The Definitive Guide To Grails is finally available from Apress. The book is a well written easy read that provides a great foundation for Grails developers.
Manning's Groovy In Action (GINA) has been available through their Early Access Program for several months now. The final version of GINA will be available in the next month or so.
Things are heating up in the Groovy and Grails communities. Look for a lot of exciting things to be happening around Grails soon.

Grails 0.3 was released today. A lot of work went in to this release which addresses over 100 bugs and feature requests. In my opinion, the fact that Grails is currently at 0.3 is a little misleading. The framework is very powerful and stable. There is a lot on the horizon but the tool is very powerful in its current state. Give it a spin.
I have recently joined the Grails development team and I am looking forward to what the future has in store for Grails.

I have committed code to Grails to support a declarative syntax for imposing restrictions on which controller actions may be invoked using which http request methods. See the docs for details.
Saturday, October 21, 2006
I have worked up an enhancement to Grails recently that provides an easy declarative way for application authors to limit access to certain controller actions based on the http request method (PUT, POST, GET, etc...). Generally speaking, applications should not allow destructive operations to be initiated in response to a GET. That isn't the only reason to want to impose restrictions, but it is a common one. With Grails, the only way to deal with this is to put code in your controller to inspect the request object and figure out if the request was a GET, POST or whatever. For the common case where all I want to do is prevent certain actions from being invoked via a GET, I don't want to have to do that. I just want to tell the framework not to allow it. The patch I have worked up does just that. The patch allows code like this in your controller...
The patch has been attached to http://jira.codehaus.org/browse/GRAILS-379.
class EmployeeController {
// action1 may be invoked via a POST
// action2 has no restrictions
// action3 may be invoked via a POST or DELETE
def httpMethodRestrictions = [action1:'POST',
action3:['POST', 'DELETE']]
def = action1 { ... }
def = action2 { ... }
def = action3 { ... }
}

My Grails presentation Thursday evening went very well. Weiqi Gao blogged about the presentation in real time.
The presentation slides are available at http://www.ociweb.com/javasig/knowledgebase/2006-09/. The tone of the whole session was very light and fun. You will see in the notes that I included quotes about Grails from famous people such as John Lennon, Mr. T, Batman and Robin and even Elvis Presley. Each time a celebrity came up in the slides I asked a trivia question about that celebrity and the first person to shout out the correct answer was given a copy of the Groovy In Action MEAP, courtesy of Manning Publishing. Thanks to Manning for those.
There are not many code samples in the presentation slides. During the presentation I built a simple application and along the way applied the concepts that are mentioned in the notes.
Before the presentation there was some discussion among the group about the future of Java and a lot of people in the group agreed that dynamic languages are going to be an important part of what we do in the future.
