Problem in getting week number

Question

I am facing a problem regarding use of Calendar object.
I have used it to calculate Week_Of_The_Year where
the week day starts with Monday. (Mon - Sun)
Its working perfectly except the last week of this year i.e. 2004
where I want it to return fiscal week 53 , but instead its returning
1 (as because the January 1-2 ' 2005 lies in that specific week.)
and in the same manner its giving problem for the first week of the
next year i.e. 2005 .Its returning Fiscal week(FW) 2 for the
January 3-9 ' 2005 period where as I want it to return FW 1 for that
week.
here is the code snippet,
         public int getWeekNumber(String dateString) {
          Calendar cal = Calendar.getInstance();
          java.util.Date dt = new java.util.Date(dateString);
          cal.setTime(dt);
          cal.setFirstDayOfWeek(Calendar.MONDAY);
          int weekNumber = cal.get(Calendar.WEEK_OF_YEAR);
          return weekNumber;
where as date string is in mm/dd/yyyy pattern.
Please, let me know if I could clearly explain the problem to you .
I am stuck with this problem with quite some time. If anybody can crack this
problem i will be grateful.
Thanks in advance.

Haven't tried it, but have you tried playing with Calendar's setMinimalDaysInFirstWeek method? That is supposed to specify how many days must be in that first week of the year. You may need to read the Calendar API more closely.
