I just did this with a small method loaded into our Base JSP page (see
following code) and a bit of trickery with the Calendar class in the JSP
(see code below). In our case we needed to get the difference between the
two dates returned as an int. If this isn't self explanatory - please ask
further questions and maybe I will be able to help.
METHOD:
//item Date is a date that comes from our DB as object Date (I believe we
are using Oracle)
public int getAge(Date itemDate)
{
//getTime() converts the date into milliseconds (from the Date class - see
the JavaDoc)
//the division creates a number to the nearest day out of the millesecond
conversion
Long oldDateLong = new Long(itemDate.getTime()/1000/60/60/24);
int oldDate = oldDateLong.intValue();
Date sysDate = new Date();
Long currDateLong = new Long(sysDate.getTime()/1000/60/60/24);
int currDate = currDateLong.intValue();
return currDate - oldDate;
}
JSP TEST PAGE:
<html>
<body>
Item Date: 1/2/2001
<!-- had to use Calendar as some of the Date class methods were deprecated
(see the JavaDoc) -->
<!-- in our "real" app the date will be fed in from a data bag - this was
just a hard coded test -->
<% Calendar Cal = Calendar.getInstance();
Cal.set(Calendar.MONTH, Calendar.FEBRUARY);
Cal.set(Calendar.DATE, 2);
Cal.set(Calendar.YEAR, 2001);
Date itemDate = Cal.getTime();
%>
Age = <%= getAge(itemDate) %>
</body>
</html>
=====================
Hope this helps (versus the pissing contest that seems to be going on
between Michael and Joseph at the moment).
Cheers, Janet
