Sending Mail

To send an email we need to use code created by others. When people want to share code, they often compile it and compress it as a library file (known as JAR file). We dont include it as we include as we would just a class (because its compiled).

• The JAR file that you need to use is here. (SAVE IT TO YOUR FOLDER THAT YOU ARE WORKING WITH)
• In BLUEJ - click preferences - Add library and find that jar file.

Have these imports:

import javax.mail.*;
import javax.mail.internet.*;
import java.util.Properties; 

Now add the code below as a method and call it. Replace the username pwd with yours if you want.

    public void sendMail(String to, String subject, String body){
        try{
            final String SMTP_HOST_NAME = "smtp.gmail.com";
            final int SMTP_HOST_PORT = 465;
            final String SMTP_AUTH_USER = "deeringCS@gmail.com";
            final String SMTP_AUTH_PWD  = "mrborland";

            Properties props = new Properties();
            props.put("mail.transport.protocol", "smtps");
            props.put("mail.smtps.host", SMTP_HOST_NAME);
            props.put("mail.smtps.auth", "true");

            Session mailSession = Session.getDefaultInstance(props);
            mailSession.setDebug(true);
            Transport transport = mailSession.getTransport();

            MimeMessage message = new MimeMessage(mailSession);
            message.setSubject(subject);
            message.setContent(body, "text/plain");

            message.addRecipient(Message.RecipientType.TO,
                new InternetAddress(to));

            transport.connect
            (SMTP_HOST_NAME, SMTP_HOST_PORT, SMTP_AUTH_USER, SMTP_AUTH_PWD);

            transport.sendMessage(message,
                message.getRecipients(Message.RecipientType.TO));
            transport.close();
        }
        catch (Exception e){}
    }
