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 DelhiWhere is the Taj Mahal?/AgraHere 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.javaTo run, write:
java -classpath .;C:installjavamailmail.jar SendMailExample
THis will do 🙂
