Answer 3

<%=Date2Week(getShortDate(scp.getTime()))%>getShortDate法是这样
 public static String getShortDate(long lngTime)
    {
        return getShortDate(new Date(lngTime));
    }Date2Week方法如下
 public static String Date2Week(String ymd) {
        try {
            Date date = df.parse(ymd);
            return df_week.format(date);
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            return null;
        }
    }其中public static SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd"); 
public static SimpleDateFormat df_week = new SimpleDateFormat("E");现在ok了
