Sending attachments with emails in Javamail

[Ajay Saxena]

I'm trying to send attachments with emails using Javamail. Following is the code through which I'm trying to achieve that. It works as expected on a JRE1.6 environment. But on JRE1.5, the content of the file gets added to the mail body as text

Any pointers on the observed difference in behavior would be highly appreciated!

 String msgText = mailInfo.getMessage();
        String attachmentFileName = mailInfo.getFileName();
        MimeBodyPart mimeBodyPart = new MimeBodyPart();
        mimeBodyPart.setText(msgText);
        // create the second message part
        MimeBodyPart attachmentBodyPart = new MimeBodyPart();
        // attach the file to the message

        FileDataSource fileDataSource = new FileDataSource(attachmentFileName);
        attachmentBodyPart.setFileName(fileDataSource.getName());
        attachmentBodyPart.setDataHandler(new DataHandler(fileDataSource));
        // attachmentBodyPart.setContent(mp);

        // create the Multipart and add its parts to it
        Multipart multipart = new MimeMultipart();
        multipart.addBodyPart(mimeBodyPart);
        multipart.addBodyPart(attachmentBodyPart);

        message.setContent(multipart);

The email in case of JRE1.5 is as follows
