JEE6 (Java Server Faces (JSF 2.0), EJB′s 3.1 en JPA 2.0)

Do you want to get started with JEE6, including JSF2 and JPA2? Here is how you can setup a first simple project using Maven als buildtool.

A sample project can also be download, by this URL.

First of all we need the pom.xml; in which the dependencies are configured. Note that we use the Jetty plugin for testing purposes. The can be started through the maven command “mvn jetty:run”.

Secondly we need a beans.xml file, which will be empty if we use annotation based configuration.

<?xml version="1.0" encoding="UTF-8"?>
<!-- The contents of this file is permitted to be empty.
