Title: JPA Eclipselink
-*Help us document this example! Click the blue pencil icon in the upper right
to edit this page.*
+This example shows how to configure `persistence.xml` to work with
Eclipselink. It uses an `@Entity` class and a `@Stateful` bean to add and
delete entities from a database.
-## Movie
+## Creating the JPA Entity
+
+The entity itself is simply a pojo annotated with `@Entity`. We create one
pojo called `Movie` which we can use to hold movie records.

+This operation is too easy, just set the `provider` to
`org.eclipse.persistence.jpa.PersistenceProvider` and add additional properties
to the persistence unit.
+The example has followed a strategy that allows the creation of tables in a
HSQL database.
