Hi Friend,

Try the following code:


<%@ page import="java.sql.*" %>
<script type="text/javascript">
function showEmp(emp_value){
if (xmlHttp==null){
alert ("Browser does not support HTTP Request")
var url="getvalue.jsp"
alert("Please Select Employee Id");
function stateChanged(){
document.getElementById("email").value ="";
document.getElementById("address").value ="";
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete") {
var showdata = xmlHttp.responseText;
var strar = showdata.split(":");
alert("Please Select Employee Id");
document.getElementById("email").value =" ";
document.getElementById("address").value =" ";
else if(strar.length>1) {
var strname = strar[1];
document.getElementById("address").value= strar[1];
document.getElementById("email").value= strar[2];

function GetXmlHttpObject(){
var xmlHttp=null;
xmlHttp=new XMLHttpRequest();
catch (e) {
try {
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
catch (e) {
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
return xmlHttp;
<form name="employee">
<table border="0" width="400px" align="center" bgcolor="#CDFFFF">
<div id="mydiv"></div>
<tr><td><b>Select Employee Name</b></td><td>
<select name="name" onchange="showEmp(this.value);">
<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>
<tr><td ><b>Employee Address:</b></td><td>
<input type="text" name="address" id="address" value=""></td></tr>
<tr><td><b>Employee Email:</b></td><td>
<input type="text" name="email" id="email" value=""></td></tr>
