Sending an email from Java using Gmail is easy.

This is how it is done.

You need the JavaMail API and the JavaBeans Activation Framework (JAF) (included in Java SE 6).

My example below.

package au.id.paulshipley.SendMail;

import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class JavaMailApp2 {
	public static void main(String[] args) {
		Properties props = new Properties();
		props.put("mail.smtp.host", "smtp.gmail.com");
		props.put("mail.smtp.socketFactory.port", "465");
		props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
		props.put("mail.smtp.auth", "true");
		props.put("mail.smtp.port", "465");

		Session session = Session.getDefaultInstance(props,
				new javax.mail.Authenticator() {
					protected PasswordAuthentication getPasswordAuthentication() {
						return new PasswordAuthentication(
								"your.name@gmail.com",
								"passwordgoeshere");
					}
				});

		try {
			Message message = new MimeMessage(session);
			message.setFrom(new InternetAddress("Your Name <your.name@gmail.com>"));
			message.setRecipients(Message.RecipientType.TO, 
                              InternetAddress.parse("Their Name <their.name@anymailserver.com>"));
			message.setSubject("Testing Subject");
			message.setText("Test message");

			Transport.send(message);

			System.out.println("Done");

		} catch (MessagingException e) {
			throw new RuntimeException(e);

		}
	}
}
