In a production site you always want to have minified and obfuscated code (i.e. CSS and JavaScript files) so that the file content is as small as possible because this will save bandwidth and loading time. The best known and easiest tool for this is the YUI Compressor from Yahoo!.
In a Java Enterprise application, the YUI Compressor can be integrated very easy with Maven. All you need is the Maven Minify Plugin. That’s how to use it:
