If the date's a string, then the sorting probably won't work right, but that strictly depends on the date format. Some date formats will sort alphabetically into the right order (e.g. yyyy-mm-dd hh:mm:ss.S will sort properly, as long as the months and days are zero-padded to two characters), but if you have a date in U.S. format, e.g. November 10, 2005, the sorting won't work on the date but on the alphabetical order of the string. You can use the decorator or JSTL tag to render a proper Date object into the correct format with the sorting on the date property or use the sortProperty attribute to sort on something else that would give you the proper sort order. In practice, you'd do the first (i.e. use a decorator or tag to render a date and just sort on that).
