In this Mastering Grails installment, Scott Davis shows you how to create your own Grails plug-in. Once you see how effortless it is to create a plug-in, you'll understand why more than 250 Grails plug-ins are available now, with new ones being added all the time.

The ability to add new methods to classes dynamically at run time — even Java classes, and even final Java classes — is incredibly powerful. Whether used for production code, unit tests, or anything in between, Groovy's metaprogramming capabilities should pique the curiosity of even the most jaded Java developer.

To be a successful software developer in this day and age, you need a set of tools that makes dealing with XML effortless. Groovy introduces new and better ways to create and process XML. With the help of some examples, this article shows you how Groovy makes building and parsing XML refreshingly simple.
