Hi Friend,

Try the following code:

1)ajax.jsp:
<html>
<body>
<script language="javascript" type="text/javascript">
function ajaxFunction(){
var ajaxRequest;
try{
ajaxRequest = new XMLHttpRequest();
}catch (e){
try{
ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
}catch (e) {
try{
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
}catch (e){
return false;
}
}
}
ajaxRequest.onreadystatechange = function(){
if(ajaxRequest.readyState == 4){
var ajaxDisplay = document.getElementById('ajaxDiv');
ajaxDisplay.value = ajaxRequest.responseText;
}
}
var name= document.getElementById("name").value;
window.open("http://localhost:8080/examples/jsp/insert.jsp?name="+name,"mywindow","width=500

, height=350,toolbar=no,resizable=yes,menubar=yes");

}
</script>
<form name="myForm">
Enter Name: <input type="text" id="name" /> <br />
<input type="button" onclick="ajaxFunction()" value="Insert"/>
</form>
</body>
</html>

2)insert.jsp:
<%@page import="java.sql.*"%>
<%
String name=request.getParameter("name");
out.println(name);
Connection conn = null;
String url = "jdbc:mysql://localhost:3306/";;;
String dbName = "register";
String driver = "com.mysql.jdbc.Driver";
String userName = "root";
String password = "root";

try {
Class.forName(driver).newInstance();
conn = DriverManager.getConnection(url+dbName,userName,password);
Statement st = conn.createStatement();
int i=st.executeUpdate("insert into Person(name) values('"+name+"')");
}
catch(Exception e){}

%>

Thanks
