another question, the JPQL query seems rarely function well, i checked if i
use:
List<Person> rl =
em.createQuery( "select o from Person o" ).setFirstResult(
startIndex ).setMaxResults( maxCount ).getResultList();
my first query using the startIndex=0; and maxCount=35, it return 35
objects, the next time i invoke this method using startIndex=0 and
maxCount=55, it still return 35 objects. what's wrong with it?
