Requirements: ColdFusion 8.0.1 or Railo 3 Installing CF Groovy is simple. Just drop groovy-all-X.Y.Z.jar in your /WEB-INF/lib folder, import the 'tags' directory as a taglib with CFIMPORT, and run the script tag with embedded Groovy (a la CFSCRIPT). For more performance, particularly in production, you'll want to manage your own instance of cfgroovy.cfc.
