NetBeans offers a real cool feature called Code Templates. This feature is available throughout the whole IDE. In my series, I explain it within the context of Java EE, but you might use it anywhere.

During the next few moth, I’m going to attend the JavaLand  conference as well as the Parallel 2015 . The first one resides in my home town. It’s a conference about various up-to-date Java topics. And you might meet some members of the JSF expert group there.
