JSP Calender Application

[amits]

Hi...

m trying to build a web application wherein users can check their college timetable...

Here's the code m using for Calender view for the user...


<%!
public int nullIntconv(String inv)
{
int conv=0;

try{
conv=Integer.parseInt(inv);
}
catch(Exception e)
{}
return conv;
}
%>
<%
int iYear=nullIntconv(request.getParameter("iYear"));
int iMonth=nullIntconv(request.getParameter("iMonth"));

Calendar ca = new GregorianCalendar();
int iTDay=ca.get(Calendar.DATE);
int iTYear=ca.get(Calendar.YEAR);
int iTMonth=ca.get(Calendar.MONTH);

if(iYear==0)
{
iYear=iTYear;
iMonth=iTMonth;
}

GregorianCalendar cal = new GregorianCalendar (iYear, iMonth, 1);

int days=cal.getActualMaximum(Calendar.DAY_OF_MONTH);
int weekStartDay=cal.get(Calendar.DAY_OF_WEEK);

cal = new GregorianCalendar (iYear, iMonth, days);
int iTotalweeks=cal.get(Calendar.WEEK_OF_MONTH);

%>


<form name="cal" method="post" id="cal">

<table width="40%" border="0" cellspacing="0" cellpadding="0" class="ieh-fl">

{
%>
<option value="<%=iy%>" selected="selected"><%=iy%></option>

<table align="center" border="1" cellpadding="3" cellspacing="0" width="100%">

<%
int cnt =1;
for(int i=1;i<=iTotalweeks;i++)

{
if(cnt<weekStartDay || (cnt-weekStartDay+1)>days)

%>
</tbody>
</table></td>

<tr>

</table>
</form>
