Sending an email with an attachment using javamail API

Question

I am trying to send an email with an attachment file in Java.

When I send the email without an attachment I receive the email, but when I add the attachment I don't receive anything and I don't get any error messages.

This is the code I am using:

public void send () throws AddressException, MessagingException{
    //system properties

Properties  props = new Properties();
props.put("mail.smtp.localhost", "localhost"); 
props.put("mail.smtp.host",Configurations.getInstance().email_serverIp); 


/*
 *  create some properties and get the default Session
 */
session = Session.getDefaultInstance(props, null);

//session
Session session = Session.getInstance(props, null);

Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("[email protected]"));
message.setRecipients(Message.RecipientType.TO,
        InternetAddress.parse("[email protected]"));
message.setSubject("Testing Subject");
message.setText("PFA");

MimeBodyPart messageBodyPart = new MimeBodyPart();

Multipart multipart = new MimeMultipart();
   generateCsvFile("/tmp/test.csv"); 
messageBodyPart = new MimeBodyPart();
String file = "/tmp/test.csv";
String fileName = "test.csv"; 
DataSource source = new FileDataSource(file);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(fileName);
multipart.addBodyPart(messageBodyPart);

message.setContent(multipart);

System.out.println("Sending");

Transport.send(message);

System.out.println("Done");

}

private static void generateCsvFile(String sFileName)
{
    try
    {

    FileWriter writer = new FileWriter(sFileName);

    writer.append("DisplayName");
    writer.append(',');
    writer.append("Age");
    writer.append(',');
    writer.append("YOUR NAME");
    writer.append(',');

    writer.append('\n');
    writer.append("Zou");
    writer.append(',');
    writer.append("26");
    writer.append(',');
    writer.append("zouhaier");


    //generate whatever data you want

    writer.flush();
    writer.close();
    }
    catch(IOException e)
    {
         e.printStackTrace();
    } 
 }

How can I correct this?

        String Password = "............";
        String from = "[email protected]";
        String toAddress = "[email protected]";
        String filename = "C:/SendAttachment.java";
        // Get system properties
        Properties props = System.getProperties();
        props.put("mail.smtp.host", host);
        props.put("mail.smtps.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        Session session = Session.getInstance(props, null);

        MimeMessage message = new MimeMessage(session);

        message.setFrom(new InternetAddress(from));

        message.setRecipients(Message.RecipientType.TO, toAddress);

        message.setSubject("JavaMail Attachment");

        BodyPart messageBodyPart = new MimeBodyPart();

        messageBodyPart.setText("Here's the file");

        Multipart multipart = new MimeMultipart();

        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);

        try {
            Transport tr = session.getTransport("smtps");
            tr.connect(host, from, Password);
            tr.sendMessage(message, message.getAllRecipients());
            System.out.println("Mail Sent Successfully");
            tr.close();

        } catch (SendFailedException sfe) {

            System.out.println(sfe);
        }
    }
    public static void main(String args[]){
        try {
            SendMail sm = new SendMail();
        } catch (MessagingException ex) {
            Logger.getLogger(SendMail.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
