you can modify the implementation of getPressReleases (in Util.java) to sort the collection before returning it.

at the end of getPressReleases in Util.java add:


Collections.sort(result, new Comparator() {
    public int compare(PressReleaseBean prb1, PressReleaseBean prb2) {
           return prb1.getLaunchDate().compare(prb2.getLaunchDate());
    }
});
‍‍‍‍‍‍‍

see http://java.sun.com/j2se/1.5.0/docs/api/java/util/Collections.html
for more information on how to sort lists.

I do it follow your way,but appear two error:

the method on Date is compareTo, not compare. my mistake.

what version of the jdk are you using? the code i'm providing is for jdk1.5.

if you are using an older jdk this should work.


Collections.sort(result, new Comparator() {
    public int compare(Object o1, Object o2) {
           return ((PressReleaseBean)o1).getLaunchDate().compareTo(((PressReleaseBean)o2).getLaunchDate());
    }
});
