BeanComparator relies on an internal Comparator to perform the ACTUAL comparisions. By default, org.apache.commons.collections.comparators.ComparableComparator is USED which imposes a natural order. If you want to change the order, then a custom Comparator should be created and passed into the appropriate constructor.

For example:

import org.apache.commons.collections.comparators.ComparableComparator;
import org.apache.commons.collections.comparators.ReverseComparator;
import org.apache.commons.beanutils.BeanComparator;
...
BeanComparator reversedNaturalOrderBeanComparator
= new BeanComparator("PROPERTYNAME", new ReverseComparator(new ComparableComparator()));
Collections.sort(myList, reversedNaturalOrderBeanComparator);
