Question

I looked at many entries on the internet without having luck.

Here is my code:

import java.io.IOException;
import java.util.Properties;

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

public class MailTest
{

    public static void main(String[] args) throws AddressException, MessagingException, IOException
    {
        String host = "***";
        String from = "b";
        String to = "***";

        // Get system properties
        Properties props = System.getProperties();

        // Setup mail server
        props.put("mail.smtp.host", host);

        // Get session
        Session session = Session.getDefaultInstance(props, null);

        // Define message
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
        message.setSubject("Hello JavaMail");
        message.setText("Welcome to JavaMail");

        // Handle attachment 1
        MimeBodyPart messageBodyPart1 = new MimeBodyPart();
        messageBodyPart1.attachFile("c:/Temp/a.txt");

        // Handle attachment 2
        MimeBodyPart messageBodyPart2 = new MimeBodyPart();
        messageBodyPart2.attachFile("c:/Temp/b.txt");

        MimeMultipart multipart = new MimeMultipart("related");

        multipart.addBodyPart(messageBodyPart1);
        multipart.addBodyPart(messageBodyPart2);

        message.setContent(multipart);

        // Send message
        Transport.send(message);
    }
}

The result is that i only get the first file attached.

1. I tried calling the attachFile method more than once but then it only applies the last attachment
2. I tried playing with the indexes at addBodyPart: no help

I checked the plain message and i see the other file in it with the same identifier and it is not listed in the attachments for some reason.

Any help would be appreciated,
Dave

Multipart multipart = new MimeMultipart("mixed");
for (String str : attachment_PathList) {
    MimeBodyPart messageBodyPart = new MimeBodyPart();
    DataSource source = new FileDataSource(str);
    messageBodyPart.setDataHandler(new DataHandler(source));
    messageBodyPart.setFileName(source.getName());
    multipart.addBodyPart(messageBodyPart);
}
msg.setContent(multipart);
Transport.send(msg);
