Hi Friend,

Try the following code:

1)ajax.jsp:

<%@page import="java.sql.*"%>
<html>
<head>
<script type="text/javascript">
function showData(value){ 
xmlHttp=GetXmlHttpObject()
var url="getdata.jsp"
url=url+"?name="+value
xmlHttp.onreadystatechange=stateChanged 
xmlHttp.open("GET",url,true)
xmlHttp.send(null)
}
function stateChanged() { 
if(xmlHttp.readyState==4 || xmlHttp.readyState=="complete"){ 
    var showdata = xmlHttp.responseText; 
    var strar = showdata.split(":");
    document.getElementById("age").value= strar[1];
    document.getElementById("city").value= strar[2];

 } 
}
function GetXmlHttpObject(){
var xmlHttp=null;
try {
  xmlHttp=new XMLHttpRequest();
 }
catch (e) {
 try  {
  xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
  }
 catch (e)  {
  xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
 }
return xmlHttp;
}
</script>
</head>
<body>
<form name="employee">
<br><br>
<table >
<div id="mydiv"></div>
   <tr><td><b>Name:</b></td><td> 
 <input  type="text" name="name" id="name" onkeyup="showData(this.value);"></td></tr>
<tr><td ><b>Age:</b></td><td>
<input  type="text" name="age" id="age" ></td></tr>
<tr><td><b>City:</b></td><td>
<input  type="text" name="city" id="city" ></td></tr>
</table>
</form>    
<table border="0" width="100%" align="center">
<br>
<br>
</table>
</body>
</html>

2)getdata.jsp:

<%@ page import="java.sql.*" %> 
<%
String name = request.getParameter("name").toString();
String data ="";
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
           Connection con = DriverManager.getConnection("jdbc:odbc:student");
           Statement st=con.createStatement();
           ResultSet rs=st.executeQuery("select * from data where name='"+name+"'");
while(rs.next())
{
data =":"+Integer.toString(rs.getInt("age")) + ":" + rs.getString("city");
}


out.println(data);
}
catch (Exception e) {
System.out.println(e);
}
%>

In the above code, when you enter the name in first field then remaining fields will get populated automatically.

Thanks
