Netbeans 6.x brought nice features and let the web development much easier. You can create many things in a “.VS-style”, in other words, drag-and-drop components on the User Interface. A good example of this it is the Visual Java Server Faces features from NetBeans 6 and the Web Service module.
Netbeans also brought Glassfish Application Server as its official server. Glassfish is the the RI (Reference Implementation) from JEE 5, therefore it is the better choice when you want to work with EJB 3.
