I want to make a simple program where you can send email from the Command Line. I found this tutorial, ‘ http://www.tutorialspoint.com/java/java_sending_email.htm ‘, however the downloads don’t. So where can I get JavaMail API and Java Activation Framework (JAF) and how would i put it in my class path.
Basically Im looking for someone to break it down and show me how I could make an email program.
Im using Eclipse luna.

Do have a look at this example. This example, simply sends one attachment as a mail. The contents of attachment quiz.txt are as follows:
What is the Capital of India?/New Delhi Where is the Taj Mahal?/Agra
Here is the SendMailExample.java file:
import java.util.*;
import javax.activation.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
public class SendMailExample {
private String from;
private String to;
private String subject;
private String messageBody;
private String fileName;
private String host;
private Properties properties;
private MimeMessage message;
private BodyPart messageBodyPart;
private Multipart multipart;
private Authenticator authenticator;
public SendMailExample () {
from = "sender@gmail.com";
to = "recipient@gmail.com";
subject = "Subject Testing";
messageBody = "<html><body><h1>HAVE FAITH, AND STAY" +
" CALM :-) I AM WITH YOU, OKAY :-)</h1></body></html>";
fileName = "quiz.txt";
host = "smtp.gmail.com";
authenticator = new SMTPAuthenticator ();
properties = System.getProperties ();
properties.put ( "mail.smtp.host", host );
properties.put ( "mail.smtp.starttls.enable", "true" );
properties.put ( "mail.smtp.port", "587" );
properties.put ( "mail.smtp.auth", "true" );
}
private void sendMail ( String from, String to,
String subject, String messageBody, String fileName ) {
try {
Session session = Session.getDefaultInstance ( properties, authenticator );
message = new MimeMessage ( session );
message.setFrom ( new InternetAddress ( from ) );
message.addRecipient ( Message.RecipientType.TO,
new InternetAddress ( to ) );
message.setSubject ( subject );
multipart = new MimeMultipart ();
messageBodyPart = new MimeBodyPart ();
messageBodyPart.setContent ( messageBody, "text/html" );
multipart.addBodyPart ( messageBodyPart );
messageBodyPart = new MimeBodyPart ();
DataSource source = new FileDataSource ( fileName );
messageBodyPart.setDataHandler ( new DataHandler ( source ) );
messageBodyPart.setFileName ( fileName );
multipart.addBodyPart ( messageBodyPart );
message.setContent ( multipart );
Transport.send ( message );
System.out.println ( "Message send successfully...." );
} catch ( Exception me ) {
me.printStackTrace ();
}
}
private void performTask () {
sendMail ( from, to, subject, messageBody, fileName );
}
public static void main ( String[] args ) {
new SendMailExample ().performTask ();
}
}
/**
* SimpleAuthenticator is used to do simple authentication
* when the SMTP server requires it.
*/
class SMTPAuthenticator extends Authenticator {
private static final String SMTP_AUTH_USER = "example@gmail.com";
private static final String SMTP_AUTH_PASSWORD = "somepassword";
public PasswordAuthentication getPasswordAuthentication () {
String username = SMTP_AUTH_USER;
String password = SMTP_AUTH_PASSWORD;
return new PasswordAuthentication( username, password );
}
}
You simply needed this mail.jar file.
To compile, simply write ( mail.jar is present at C:installjavamailmail.jar` location ):
javac -classpath .;C:installjavamailmail.jar SendMailExample.java
To run, write:
java -classpath .;C:installjavamailmail.jar SendMailExample
THis will do 🙂
