@Table(name="PERSON",schema="test")

@Id
private int id;
@Column(name="NAME")
private String name;

private String family;
public Person() {
}

return family;
}

this.family = family;
}

}
}

Person person = new Person();
try {

person.setId(1);
person.setName("babak");
person.setFamily("azarmi");
em.persist(person);
em.getTransaction().commit();
} catch (Exception ex) {
if (em.getTransaction().isActive()) {
em.getTransaction().rollback();
}
ex.printStackTrace();
} finally {
try {
em.close();
} catch(Exception ex) {
}
}
}
/**

public static void main(String[] args) {
new Main();
}
}
