Interacting with Databases through the Java Persistence API - Java EE 5 Development with NetBeans 6 - page 207

After clicking Finish , a complete web application that can perform CRUD operations
will be created.
As we can see, NetBeans generates a folder for each of our entities under the Web
Pages folder of our application. Each of the folders has a Detail , Edit , List , and
New JSP files. The Detail JSP will display all properties for a JPA entity, the Edit
JSP will allow users to update information for a specific entity, the List JSP will
display all instances of a specific entity in the database, and the New JSP will provide
functionality to create new entities.
