The answer can be found in sticky post of JSP section

as suggested by adatapost here i'm posting the code which i used...

<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>

		{
			Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

			String sql="select * from message_box where name='anindo'";
			rs=stat.executeQuery(sql);
			%>
<script language="javascript">
function check()
{
	var show=document.getElementById("mydivtag");
	show.innerHTML = "<label><select name=select><% while(rs.next()){%><option><%= rs.getString(1) %></option><option><%= rs.getString(2) %></option><option><%= rs.getString(3).substring(0,10) %></option></select></label><%}}catch(Exception ex){out.print("Exception is:- "+ex);}%>";
}
</script>
</head>
<body>
<form id="form1" name="form1" method="post" action="try.jsp">
  <label></label>
  <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
    <input type="submit" name="Submit" value="Submit" onclick="check()" />
	  </p>
  <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
   

   </p>
  <div id="mydivtag" ></div>
  <p>&nbsp;</p>
</form>
</body>
</html>

i have used p_portal as the dsn and the database table message_box described as below..

name varchar 50
from varchar 50
subject varchar 1000
date datetime 8

i hope the code will make the things very clear.....

HTML tag - </select> must be placed outside the while loop.

show.innerHTML = "<label><select name='select'><% while(rs.next()){%><option><%= rs.getString(1) %></option><option><%= rs.getString(2) %></option><option><%= rs.getString(3).substring(0,10) %></option><%}}catch(Exception ex){out.print("Exception is:- "+ex);}%></select></label>";

hello adatapost...

i'v modified the code....but still there's a problem

when i'm clicking the button......a drop down menu wid the loaded data is appearing but as soon as the page is fully loaded the drop down menu disappears....i'm not getting hold of this problem....

indeed , am not using MVC structure but i have done what you want before, you can take a look

<select name="select" size="1" >
<%
 String sql = "select *from  table ";

   Vector v1=database.jdbcMultipleRowQuery(sql);
	for(int i=0;i<v1.size();i++){
	Vector  v2 = (Vector)v1.elementAt(i);
for(int j=0;j<v2.size();j++){

out.print("<option>"+v2.get(0)+"</ption>");		
		
}
}
%>

it may help

Use input type button:

<input type="button" name="submit" value="Submit" onclick="check()" />
