Subject Re: Using date to format a date
Date Mon, 19 Oct 2009 14:18:13 GMT
What I do is add a method for formatting dates (formatDateTime()) to the
action base class.  The method can then use the users Locale and TimeZone to
construct a DateFormat object.

    public String formatDateTime(Date timestamp)
    {
        return getDateFormat().format(timestamp);
    }

In the jsp I then I can then format the date ('updated' in this case) like
this:

<s:property value="formatDateTime(updated)" />

If you already have a DateFormat object around you could create a method in
you action that takes both the Date and the DateFormat.

Note: Be careful storing DateFormat in the Session as DateFormat is not
synchronized so it can not used concurrently by multiple threads.
