JSF 2.0 Development 
The NetBeans IDE supports Facelets, the official view technology for JSF 2.0.
You can create a new web application project based on the Facelets framework
and work with standard JSF reference implementation components.
This includes a comprehensive library of JavaServer Faces components such as
Table, Calendar, Tree, Tab Set, File Upload, and more.
The IDE comes with an editor for deployment descriptors (web.xml files)
and an HTTP monitor for tracking and debugging the data flow between components of a web app.
JSF Code Generation and Palettes
Use the JSF CRUD application generator (Create/Read/Update/Delete)
to create a complete functional JSF page
for manipulating data from a database.
The New File wizard can generate customizable CRUD
JSF pages from existing entities.
Use the customizable HTML and JSF components palettes to drag and drop
HTML and JSF forms into web pages,
and let it generate JSF data tables from entities.
The IDE now generates code using annotations
instead of deployment descriptors where possible.
Enterprise Java Beans (EJB) Development 
The IDE now supports EJB 3.1 in web application projects
and the EJB project file wizard also offers the Singleton session type.
Use a wizard to easily create a Session Bean for an entity class
including appropriate annotations and commonly used default methods.
You can expose the bean with a local interface or a no-interface view.
Java Persistence
The IDE provides tools to work with the Java Persistence API 2.0.
Wizards enable you to generate entity classes from a database,
and a JavaServer Faces CRUD (Create Retrieve Update Delete) application
from entity classes.
The IDE supports all types of entity relationships (one-to-one, one-to-many, many-to-one, and many-to-many)
and all types of primary keys (single-column, composite, and generated).
The IDE also provides templates and graphic editors for creating and maintaining persistence units.
