I have created a calendar program in jsp.
I have 3 problems now..

1. the calendar is displaying all the months vertically, but i need it to be shown in 3*4 matrix style, ie.. jan feb mar on one row,like that.

2. I want the user to select the dates(multiple selection needs to be done), when he selects the date, that date has to be highlighted with some color, to know it is clicked.

3. I should be able to transfer those dates to another jsp page, how to transfer the selected date?

my calendar code is shown below :

<%@page import="java.util.*,java.text.*" %>
<html> 
<head>
<title>Print a month page.</title>
<meta name="version"</head>
<body bgcolor="white">
 
 <%
boolean yyok = false;
int yy = 0, mm = 0;
 
String yyString = request.getParameter("year");
if (yyString != null && yyString.length(  ) > 0) 
{
    try
       {
       yy = Integer.parseInt(yyString);
       yyok = true;
      }
     catch (NumberFormatException e)
     {
     out.println("Year " + yyString + " invalid");
    }
}
 
Calendar c = Calendar.getInstance(  );
if (!yyok)yy = c.get(Calendar.YEAR);   
mm = c.get(Calendar.MONTH);
%> 
 
<form method=post action="CalendarPage.jsp">
Enter Year : <input type="text" size="5" name="year" value=" <%= yy %>"></input>
<input type=submit value="Display">
</form>
<%!
 
String[] months = {"January", "February", "March", "April",
            "May", "June", "July", "August",
           "September", "October","November", "December"
          }; 
 
int dom[] = {31, 28, 31, 30,
 31, 30, 31, 31, 
30, 31, 30, 31};
%>
 
 <%
 int leadGap = 0;
%>
 <table border=1>
<%
for(int j=0;j<12;j++)
{ 
 GregorianCalendar calendar = new GregorianCalendar(yy, j, 1);
%> 
<tr>
<th colspan=7>
<%= months[j] %> 
<%= yy %>
</tr>
 
<tr>
<td>Su<td>Mo<td>Tu<td>We<td>Th<td>Fr<td>Sa</tr>
 
 <%
leadGap = calendar.get(Calendar.DAY_OF_WEEK)-1; 
int daysInMonth = dom[j];
 
if (calendar.isLeapYear(calendar.get(Calendar.YEAR)) && j == 1)
++daysInMonth; 
 
out.print("<tr>");
out.println(" ");

for (int i = 0; i < leadGap; i++) 
{
  out.print("<td> ");
}

for (int i = 1; i <= daysInMonth; i++)
 {
 out.print("<td>");
 out.print(i);
 out.print("</td>");  
 
  if ((leadGap + i) % 7 == 0) 
{ 
out.println("</tr>");
out.print("<tr>");
}
           }
}
%>
</tr>
</table>
</html>

please help with the code..

Thanks,
Venkatesh

Your first two problems are related to HTML/Javascript and you had better address these here.

What HTML component are you using to show a date? If its a table then you can take those selected tds innerHTML into some hidden field and get that value in other page using that field.
