You can use the Javamail for that. The thing to remember is that GMail uses SMTPS not SMTP.

import javax.mail.internet.*;
import java.util.Properties;
public class SimpleSSLMail {
private static final String SMTP_HOST_NAME = "smtp.gmail.com";
private static final int SMTP_HOST_PORT = 465;

public static void main(String[] args) throws Exception{
new SimpleSSLMail().test();
}
public void test() throws Exception{
Properties props = new Properties();
props.put("mail.transport.protocol", "smtps");
props.put("mail.smtps.host", SMTP_HOST_NAME);
props.put("mail.smtps.auth", "true");
// props.put("mail.smtps.quitwait", "false");
Session mailSession = Session.getDefaultInstance(props);
mailSession.setDebug(true);
Transport transport = mailSession.getTransport();
MimeMessage message = new MimeMessage(mailSession);
message.setSubject("Testing SMTP-SSL");
message.setContent("This is a test", "text/plain");
message.addRecipient(Message.RecipientType.TO,
new InternetAddress("elvis@presley.org"));
transport.connect
(SMTP_HOST_NAME, SMTP_HOST_PORT, SMTP_AUTH_USER, SMTP_AUTH_PWD);
transport.sendMessage(message,
message.getRecipients(Message.RecipientType.TO));
transport.close();
}
}
