How to use Session scope in jsp page

Question

Hello, I have login form, where user provides username and password. Then click on submit, it will forward to validation.jsp. Where it will check in database make sure username and password exit. Now i can also retrive accountid of perticular user. I want to put that username and accountid in session scope. so all other pages can use that username and accountid. How can i do that. I'm new at this, so please provide me example too. Here is my code for login.jsp and validation.jsp..
Validation.jsp
<%@ page import="java.util.*" %>
<%@ page import="java.sql.*" %>
//String name = request.getParameter( "username" );//
//session.setAttribute( "accountID",accountID );//
<%
String connURL = "jdbc:oracle:thin:@orca.csc.ncsu.edu:1521:ORCL";
     Connection conn = null;
     Statement stmt = null;
     ResultSet rs = null;
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
conn = DriverManager.getConnection(connURL, "vapatel","pjdas");
stmt = conn.createStatement();
String user=request.getParameter("userName");
String password=request.getParameter("password");
boolean entrance=false;
stmt.excuteQuery("SELECT AccountID From Password WHERE USERNAME='"+user+"'");
rs = stmt.executeQuery("SELECT * FROM Password WHERE USERNAME='"+user+"' AND PASSWORD='"+password+"'");
while(rs.next()){
String dbUser = rs.getString("USERNAME");
String dbPassword= rs.getString("PASSWORD");
if ((user.equals(dbUser)) && (password.equals(dbPassword))){
