Learn how to send email via Gmail from Java in 120 seconds.

I did a quck google check and found that there where lots of different snippets out there for sending a simple SSL email.

Here's a short snippet with all the indirections and extras to get something up'n running fast.

• Example is written for JDK 1.6 (Java 6)
• Download https://maven-repository.dev.java.net/nonav/repository/javax.mail/jars/mail-1.4.1.jar and add it to your classpath (Build path).
• Change the stuff in yellow to your own info.
• Run (Make sure you have enabled pop or imap in you gmail account)
• (Then ... write things from scratch with proper abstraction and exception handling).

    import java.io.*;
    import java.net.InetAddress;
    import java.util.Properties;
    import java.util.Date;
    import javax.mail.*;
    import javax.mail.internet.*;
    import com.sun.mail.smtp.*;
    
public class Distribution {

    public static void main(String args[]) throws Exception {
        Properties props = System.getProperties();
        props.put("mail.smtps.host","smtp.gmail.com");
        props.put("mail.smtps.auth","true");
        Session session = Session.getInstance(props, null);
        Message msg = new MimeMessage(session);
        msg.setFrom(new InternetAddress("mail@tovare.com"));;
        msg.setRecipients(Message.RecipientType.TO,
        InternetAddress.parse("tov.are.jacobsen@iss.no", false));
        msg.setSubject("Heisann "+System.currentTimeMillis());
        msg.setText("Med vennlig hilsennTov Are Jacobsen");
        msg.setHeader("X-Mailer", "Tov Are's program");
        msg.setSentDate(new Date());
        SMTPTransport t =
            (SMTPTransport)session.getTransport("smtps");
        t.connect("smtp.gmail.com", "admin@tovare.com", "<insert password here>");
        t.sendMessage(msg, msg.getAllRecipients());
        System.out.println("Response: " + t.getLastServerResponse());
        t.close();
    }
}

To easily send off emails I can really recommend using the Apache Commons package instead http://commons.apache.org/email/ package, it does a brilliant job in simplifying working with emails.


Happy hacking!
