TomEE is one of the most exciting developments in the Java EE ecosystem. For those unaware, TomEE is a very cool Apache project that starts from Tomcat and adds OpenWebBeans, OpenEJB, OpenJPA, MyFaces, Apache CXF and ActiveMQ to create a very capable Java EE environment! TomEE is one of the greatest examples of certified Java EE Web Profile implementations. It is also a great option for Java EE developers focused on Tomcat.
This great article describes how you can use TomEE with NetBeans (you can also use Eclipse, check the TomEE docs).
