Here is a jsp code that display the records into textfields according to the id entered by user.

1)ajax.jsp:

<%@page import="java.sql.*"%>
<html>
<head>
<script type="text/javascript">
function showData(){ 
xmlHttp=GetXmlHttpObject()
    var id=document.getElementById("id").value;
var url="getdata.jsp";
url=url+"?id="+id;
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(":");
      if(strar.length>1)
         {
        var strname = strar[1];
        document.getElementById("name").value= strar[1];
        document.getElementById("address").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 >
<br><br>
<table >
<tr><td>Client ID:</td><td><input type="text" id="id" name="id" onkeyup="showData();"></td></tr>
<tr><td>Name:</td><td><input type="text" id="name" name="name"></td></tr>
<tr><td>Address:</td><td><input type="text" id="address" name="address"></td></tr>
</table>
</body>

2)getdata.jsp:

   <%@ page import="java.sql.*" %> 
    <%
    int id = Integer.parseInt(request.getParameter("id"));

     String data=" ";  
     try{
      Class.forName("com.mysql.jdbc.Driver");
               Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root");
     Statement stmt = con.createStatement();  
     ResultSet rs = stmt.executeQuery("Select * from addclients where clientid  ="+id+"");  
       while(rs.next())
                    {
                        data = ":" + rs.getString("name") + ": " + rs.getString("address");
                    }
                    out.println(data);
      }
     catch(Exception e){
    System.out.println(e);
     }

 %>
