Creating Our First JPA Entity
JPA entities are Java classes whose fields are persisted to a database by the JPA
API. JPA entities are
Plain Old Java Objects
(
POJO
s), as such, they don't need to
extend any specific parent class or implement any specific interface. A Java class is
designated as a JPA entity by decorating it with the
@Entity
annotation.
In order to create and test our first JPA entity, we will be creating a new web
application using the JavaServer Faces framework. In this example we will name
our application
jpaweb
. As with all of our examples, we will be using the bundled
GlassFish application server.
Consult Chapter 4
Developing Web Applications using JavaServer Faces
for
instructions on creating a new JSF project.
To create a new JPA Entity, we need to right-click on the project and select
New | Entity Class
