Hi i am beginner to java,
My requirement is i need to scan the database changes every second and need to show the changesin the jsp,
I have started to write progrmme as below......My major problem was the data was not appending to the jsp but after exiting the while loop it shows all the results at once

the code is
<%@page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>
<%@ page import="com.project.scanchanges.*"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>EDUSOL</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<link href="styles.css" rel="stylesheet" type="text/css">
</head>
<body>

<%


while(true){
try{
ScanTags s=new ScanTags();
NameBean n=s.ReadTags(false);
if(n==null){
continue;
}

out.println(n.getName()+" has Checked "+n.getMode());
}
catch(Exception e){
out.println("Exceptioni n getting values");
e.printStackTrace();
break;
}
}

%>
</body>
</html>
