Hi Friend,

Try the following code:

1)selectbox.jsp:

<html>
<head>
<script language="javascript" type="text/javascript">
var xmlHttp
function showState(str){
if (typeof XMLHttpRequest != "undefined"){
xmlHttp= new XMLHttpRequest();
}
else if (window.ActiveXObject){
xmlHttp= new ActiveXObject("Microsoft.XMLHTTP");
}
if (xmlHttp==null){
alert ("Browser does not support XMLHTTP Request")
return
}
var url= "select.jsp";
url += "?val=" +str;
xmlHttp.onreadystatechange = stateChange;
xmlHttp.open("GET", url, true);
xmlHttp.send(null);
}
function stateChange(){
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete"){
document.getElementById("txt").value=xmlHttp.responseText;
}
}
</script>
</head>
<body>
<select onchange="showState(this.value)">
<option value="Alto">Alto</option>
<option value="Esteem">Esteem</option>
<option value="Honda City">Honda City</option>
<option value="Chevrolet">Chevrolet</option>
</select>
<br>
<input type="text" id="txt">
</body>
</html>

2)select.jsp:

<% String data=request.getParameter("val");
response.getWriter().println(data);
%>

Thanks
