I want exactly working code for sending Email with attachment in JSP, with all details.

I am using Appache tomcat Server.

And this is my code working without attachment...

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

<%@page import="javax.mail.*" %>
<%@page import="javax.activation.*" %>
<%@page import="java.security.Security" %>
<%@page import="java.util.Properties" %>
<%@page import="javax.mail.Message" %>
<%@page import="javax.mail.Session" %>
<%@page import="javax.mail.Transport" %>
<%@page import="javax.mail.internet.InternetAddress"%>
<%@page import="javax.mail.internet.MimeMessage"%>
<%@page import="java.util.Random" %>
<%@page import="javax.mail.internet.*"%>
<%@page import="java.io.*"%>

//Transport.send(message);
