Hi bellow are the 2 methods
public void testLoadPersonUsingOJB() throws Exception {
long time = System.currentTimeMillis();
final long PERSON_ID = 112327;
Person person = new Person();
Identity id = new Identity(Person.class, Person.class, new Long[]
{new Long(PERSON_ID)});
person = (Person) broker.getObjectByIdentity(id);
assertTrue(person != null);
assertTrue(null != person.getBirthday());
assertTrue(null != person.getCitizenship());
assertTrue(null != person.getCity());
assertTrue(null != person.getFirstName());
assertTrue(null != person.getName());
assertTrue(null != person.getStreet());
time = System.currentTimeMillis() - time;
System.out.println(time);
}
public void testLoadPersonUsingHibernate() throws Exception {
long time = System.currentTimeMillis();
final long PERSON_ID = 112327;
Person person = (Person) session.load(Person.class, new
Long(PERSON_ID));
assertTrue(person != null);
assertTrue(null != person.getBirthday());
assertTrue(null != person.getCitizenship());
assertTrue(null != person.getCity());
assertTrue(null != person.getFirstName());
assertTrue(null != person.getName());
assertTrue(null != person.getStreet());
assertTrue(null != person.getFullName());
time = System.currentTimeMillis() - time;
System.out.println(time);
}
the session(4 hibernate) and the broker (4 OJB) are initialized in the
constructors.

For me too!
How does your test looks like?
long time = System.currentTimeMillis();
Person person = (Person) broker.getObjectByQuery(query);
time = System.currentTimeMillis() - time;
Can you post source of both test?
