Hi Friend,

Try the following code:

<%@page import="java.sql.*"%>
<html>
<script>
function hello(){
var w = document.form.sel.selectedIndex;
var value = document.form.sel.options[w].text;
window.location.replace("select.jsp?st="+value);
}
</script>
<form name="form">
Select Employee Name:<select name="sel">
<option value="-1"><--Select--></option>
<option value="Angelina">Angelina</option>
<option value="Martina">Martina</option>
<option value="Julia">Julia</option>
<option value="Angel">Angel</option>
</select>
<input type="button" value="submit" onclick="hello();">
</form>
<%
String str=request.getParameter("st");
if(str!=null){
try {

Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test";, "root", "root");
Statement st = conn.createStatement();
ResultSet rs=st.executeQuery("Select * from employee where name='"+str+"'");

while(rs.next()){

out.println("Name= "+rs.getString("name")+"<br>");
out.println("Address= "+rs.getString("address")+"<br>");
out.println("Contact No= "+rs.getString("contactNo")+"<br>");
out.println("Email= "+rs.getString("email"));
}
}
catch(Exception e){}
}
%>

Thanks
