A Mailing application in struts is given below, This application sends an email to the recipients you specify on the local SMTP server.
To run this example you fist need to install and run the SMTP server.
To write a method to send an e-mail see the steps given below
1. Set the host smtp address like
String SMTPHost = "192.168.14.123";
2. Create properties object
Properties properties = new Properties();
3. Set mail SMTP host in properties
properties.put("mail.smtp.host", SMTPHost);
4. get the Session
Session session = Session.getDefaultInstance(properties,
null);
5. create a message
Message msg = new MimeMessage(session);
6. Set sender and Recipients address
InternetAddress addressFrom = new InternetAddress(from);
msg.setFrom(addressFrom);
7. Add all recipients
InternetAddress[] addressTo = new InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++) {
addressTo[i] = new InternetAddress(recipients[i]);
}
msg.setRecipients(Message.RecipientType.TO, addressTo);
8. Set e-mail header
msg.addHeader("MailingApplication", "Struts 2 Mailing
Application");
9. Set the Subject and Content Type
msg.setSubject(subject);
msg.setContent(message, "text/html");
Transport.send(msg);
