  • Work with Groovy strings, closures, and collections
  • See how conditionals, loops, and other control structures differ in Groovy versus Java and other languages
  • Produce and parse JSON and XML data
  • Access relational databases from Groovy
  • Understand the fundamentals of Grails and how it integrates with Spring, Hibernate, and other frameworks
  • Use domain classes and understand domain class relationships
  • Understand MVC architecture and best practices for implementing it in Grails applications
  • Build Groovy Server Pages
  • Write and use Grails services
  • Deploy a Grails application


All attendees should be familiar with web development in Java, including servlets, JSPs, and database access.


All attendees receive a copy of Apress’s The Definitive Guide to Grails 2 and related course materials, as well as copies of all code created during class.


  • JDK 1.6 or later
  • The latest stable release of Grails
  • A powerful IDE that supports Groovy and Grails, such as SpringSource’s Groovy/Grails Tool Suite or IntelliJ IDEA
  • Related free software and lab files; please contact us for detailed specifications
  • For classes delivered online, all participants need either dual monitors or a separate device logged into the online session so that they can do their work on one screen and watch the instructor on the other. A separate computer connected to a projector or large screen TV would be another way for students to see the instructor’s screen simultaneously with working on their own.
