AFAIK the only way is calculating it yourself
public static int calendarWeekIso(final Date inputDate) {
int thursdayDay = 4 + firstDayOfWeek;
Date thisThursday = new Date(inputDate.getYear(),
inputDate.getMonth(),
inputDate.getDate() - weekday(inputDate) +
thursdayDay);
Date firstThursdayOfYear = new Date(thisThursday.getYear(), 0,
1);
while (weekday(firstThursdayOfYear) != thursdayDay) {
firstThursdayOfYear.setDate(firstThursdayOfYear.getDate() + 1);
}
Date firstMondayOfYear = new
Date(firstThursdayOfYear.getYear(), 0,
firstThursdayOfYear.getDate() - 3);
Long cw = (thisThursday.getTime() - firstMondayOfYear.getTime())
/ ONE_DAY / DAYS_IN_A_WEEK + 1;
return cw.intValue();
}
