Should I just loop through the array and call save() for each object?

public void save(SomeArray[] array) {
try {
Session session = sessionFactory.openSession();
for (int i = 0; i < array.length; i++) {
session.save(array[i]);
}
} catch (HibernateException ex) {
//handle exception
}
}

Thanks!

If your array is not in fact an association from another persistent class, yes

Will setting the hibernate.jdbc.batch_size help with my performance in this method?

Thanks!

Maybe. Try it
