Dynamic scripting languages are a powerful addition to a software designer’s toolbox. Rails/Ruby and Python have not gained much acceptance in the enterprise. Grails and Groovy are an attempt to bridge the gap between the modern scripting world and the Enterprise Java world.
This talk is an introduction towards building web applications in Grails. First we will go about creating a REST based webservice. We will also show how to replace the default database backend of Grails with MySQL.
We will then build a web application that consumes this webservice. The emphasis will be on the design patterns and idioms in Grails that address the web application development lifecycle.
Clipping is a handy way to collect important slides you want to go back to later.
