Today WebM.ag is speaking with Jeff Croft, Jeff needs little introduction as he is a well known web designer and developer, an author of some top notch web design literature and he also speaks at conferences about web design/development.

The groovy.util package contains the FileNameFinder and FileNameByRegExFinder classes. We can use the FileNameFinder classe to search recursively for files in a directory with ANT fileset pattern conventions. With the FileNameByRegExFinder we use regular expressions to define the file patterns.

In Groovy we can write classes and write an implementation for methods we don't even know exist. We must implement the method methodMissing() which is invoked when other methods cannot be found.

The recent weeks I have been playing around with grails. When working with grails you have to learn groovy as well. Sometimes I am just amazed by the easiness of doing things with groovy. That is why I started out using groovy for a very small project (at least with groovy) to analyze an xml file as generated by the performance measurement framework Beet. In this blog post I go step-to-step through a solution that analyzes the xml file and plots the results in a chart generated with jfreechart.
