Hi Friend,

Try the following code:
1)calendar.jsp:

<html>
<script language="javascript" type="text/javascript" src="calendar.js">
</script>
<table>
<tr><td>Date Of Birth</td><td><input type="Text" id="demo1" maxlength="25" size="25"><a href="javascript:displayCalendar('demo1','ddmmmyyyy')"><img src="calendar.png" width="16" height="16" border="0" alt="Pick a date"></a></td>
</tr>
<tr><td>Date Of Joining</td><td><input type="Text" id="demo2" maxlength="25" size="25"><a href="javascript:displayCalendar('demo2','ddmmmyyyy')"><img src="calendar.png" width="16" height="16" border="0" alt="Pick a date"></a></td>
</tr>
</table>
