During this Groovy and Grails Primer course, you will become familiar with the features offered by the Groovy language and the Grails framework. You learn how to integrate Grails with existing Java Enterprise services, databases, and web applications and how to leverage Groovy's additional power to Java technology, and how to make writing shell and build scripts easy with Groovy's powerful processing primitives, object-oriented abilities and an Ant DSL. You learn how Groovy supports domain-specific languages and other compact syntax so your code becomes easy to read and to maintain, and how to simplify testing by supporting unit testing and mocking out-of-the-box. In addition, you learn how to integrate Grails with existing frameworks, such as Spring and Hibernate, Java Enterprise services, databases and web applications and how to use a blended approach mixing static and dynamically typed code to maximize the scalability of your code base. Come to this course to experience the power of Grails 1.0 and Groovy 1.5. This 1-day Groovy and Grails course has been developed by Grails Project lead and former Skills Matter CTO Graeme Rocher and is being kept up to date with all the latest developments by Steven DeVijver, co-founder of the Grails project.
