How do I send an e-mail in Java?

Question

I need to send e-mails from a servlet running within Tomcat. I'll always send to the same recipient with the same subject, but with different contents.

What's a simple, easy way to send an e-mail in Java?

Answer 1

Here's my code for doing that:

import javax.mail.*; import javax.mail.internet.*;  // Set up the SMTP server. java.util.Properties props = new java.util.Properties(); props.put("mail.smtp.host", "smtp.myisp.com"); Session session = Session.getDefaultInstance(props, null);  // Construct the message String to = "[email protected]"; String from = "[email protected]"; String subject = "Hello"; Message msg = new MimeMessage(session); try {     msg.setFrom(new InternetAddress(from));     msg.setRecipient(Message.RecipientType.TO, new InternetAddress(to));     msg.setSubject(subject);     msg.setText("Hi,\n\nHow are you?");      // Send the message.     Transport.send(msg); } catch (MessagingException e) {     // Error. }
