The book certainly covers a lot of NetBeans tricks to make our lives as software developers simpler.
For example, the book covers how it is possible to add resources such as
JDBC connection pools, datasources and JMS message queues directly from NetBeans.
The book also covers how to automatically generate the data layer of an application from an existing database schema.
Additionally, the book covers how to automatically generate an "ajaxified"
JSF web application from existing JPA entities.
On top of that, the book covers how to easily develop visually appealing web applications without being a CSS expert thhough the NetBeans Visual Web JSF functionality.
The above three features are only a highlifht of the NetBean features covered in the book.
