JSF:

Filter Bean:

@Named
@ApplicationScoped
public class DateRangeFilter implements Serializable {

    private static final Logger LOG = Logger.getLogger(DateRangeFilter.class.getName());

    public boolean filterByDate(Object value, Object filter, Locale locale) {

        String filterText = (filter == null) ? null : filter.toString().trim();
        if (filterText == null || filterText.isEmpty()) {
            return true;
        }
        if (value == null) {
            return false;
        }

        DateFormat df = SimpleDateFormat.getDateInstance(SimpleDateFormat.MEDIUM);

        Date filterDate = (Date) value;
        Date dateFrom;
        Date dateTo;
        try {
            String fromPart = filterText.substring(0, filterText.indexOf("-"));
            String toPart = filterText.substring(filterText.indexOf("-") + 1);
            dateFrom = fromPart.isEmpty() ? null : df.parse(fromPart);
            dateTo = toPart.isEmpty() ? null : df.parse(toPart);
        } catch (ParseException pe) {
            LOG.log(Level.SEVERE, "unable to parse date: " + filterText, pe);
            return false;
        }

        return (dateFrom == null || filterDate.after(dateFrom)) && (dateTo == null || filterDate.before(dateTo));
    }
}
