1)Getname.jsp:

<%@page import="java.sql.*"%>
<html>
<head>
<script type="text/javascript">
function showData(){ 

xmlHttp=GetXmlHttpObject()
var url="../Name";
xmlHttp.onreadystatechange=stateChanged 
xmlHttp.open("GET",url,true)
xmlHttp.send(null)
}
function stateChanged(){ 
if(xmlHttp.readyState==4 || xmlHttp.readyState=="complete"){ 
    var showdata = xmlHttp.responseText; 
    document.getElementById("name").value= showdata;
    } 
}
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 onload="showData();">
<b>Name:</b><input  type="text" name="name" id="name" >
</body>
</html>

2)Name.java:

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class Name extends HttpServlet { 
    public void doGet(HttpServletRequest req,HttpServletResponse res) throws ServletException,IOException {
        res.setContentType("text/html");
        PrintWriter out = res.getWriter();
        String data ="roseindia";
        out.println(data);
        }
    }
