Consider a simple POJO class, like the one shown below:
Class Person{
long id;
String firstName;
String lastName;
...
}
Now, suppose you want to persist a collection of
Person objects. You can do it using the following code:
EntityManagerFactory factory =
Persistence.createEntityManagerFactory("testSample");
OpenJPAEntityManager em = (OpenJPAEntityManager)
factory.createEntityManager();
em.getTransaction().begin();
List perList = new ArrayList();
perList.add(new Person(1,"firstname1","lastname1"));
perList.add(new Person(1,"firstname1","lastname1"));
em.persistAll(perList );
em.getTransaction().commit();
em.close();factory.close();
