Sending Email using JSP

This is a sample program to send email using JSP. Of course you should have a HTML page that shows a form to enter and get details of the email, just as you will see in any email client. The form should accept details such as 'to' email, 'from' email, 'subject' and 'body'. The form action should point to the JSP page shown below.

<%@ page import="java.util.*" %>
<%@ page import="javax.mail.*" %>
<%@ page import="javax.mail.internet.*" %>
<%@ page import="javax.activation.*" %>
String host = "yourmailhost";
String to = request.getParameter("to");
String from = request.getParameter("from");
String subject = request.getParameter("subject");
String messageText = request.getParameter("body");
boolean sessionDebug = false;
// Create some properties and get the default Session.
Properties props = System.getProperties();
props.put("", host);
props.put("mail.transport.protocol", "smtp");
Session mailSession = Session.getDefaultInstance(props, null);
// Set debug on the Session
// Passing false will not echo debug info, and passing True will.
// Instantiate a new MimeMessage and fill it with the
// required information.
Message msg = new MimeMessage(mailSession);
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSentDate(new Date());
// Hand the message to the default transport service
// for delivery.
out.println("Mail was sent to " + to);
out.println(" from " + from);
out.println(" using host " + host + ".");
