Griffon in Action by Andres Almiray, Danno Ferrin

Griffon in Action gets you going quickly. Griffon's convention-over-configuration approach requires minimal code to get an app off the ground, so you can start seeing results immediately. You'll learn how SwingBuilder and other Griffon "builders" provide a coherent DSL-driven development experience. Along the way, you'll explore best practices for structure, architecture, and lifecycle of a Java desktop application. Written for Java developers—no experience with Groovy, Grails, or Swing is required.
