wouldn't be simpler to have a calendar bean do the processing and
use struts to dispaly the calendar bean properties.
Class MonthlyCalender {
private Date dte
private java.util.List days = new ArrayList(42);
private int lastDay; // 31, 30, 29 or 28
private int strtPos; // 1 - 7 : day of week for the 1st of the month **
public void setDate(String d) {this.dte = new Date(d); fillDays() }
public Date getDate(return dte.toString()) ;
private void fillDays() {
int counter=1;
for (int d =0; d < 42; d++) {
if (d < strtPos -1)
days.add(""); // nice would be count back from lstday of lastmon
else
days.add(counter++);
}
}
