NetBeans and Eclipse provide tools, templates, wizards and code generators for building a Java EE 6 application. They both also allow a Java EE 6 Maven project to be created. In his recent screencast, Adam Bien explained how a Java EE 6 project can be easily created at command-line using Maven 3.

The screencast walks through the process of creating the project using command-line. The created project has no dependency on NetBeans and GlassFish but can still be opened in NetBeans and deployed on GlassFish.

A complete list of Adam's screencasts are available here. Tons of similar videos are also available on GlassFishVideos channel.
