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);
}
}
