Java Mail Question : Attachement Problems

[Lee]

Hi there,

This looks like a frequently asked question, but none of the answers I
found with a Google search seem to help. I have a class that send email
messages, but when I send attachements I encounter problems. Plain text
files just appear in the message body, where as image files appear as
"gobbeldygook" (character encoding/whatever).

Does anyone use javax.mail frequently? Can you enlighten me as to what
my problem is? Snippets below:

-------------------------

msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(from));
msg.setSubject(subject);
msg.setSentDate(new Date());
msg.setRecipients(MimeMessage.RecipientType.TO, addressList);

MimeBodyPart mbp1 = new MimeBodyPart();
mbp1.setText(messageBody, "us-ascii");
MimeMultipart mp = new MimeMultipart();
mp.addBodyPart(mbp1);
if...
{
for...
{
MimeBodyPart mbp2 = new MimeBodyPart();
ataSource source = new FileDataSource(attArr);
mbp2.setDataHandler(new DataHandler(source));
mbp2.setFileName(attArr);
mp.addBodyPart(mbp2);
}
}

msg.setContent(mp);
----------------------------

Do you think the problem may reside in the recieving end
while processing or getting the attachments? May be the
disposition of the attachments are set to inline? What do
you think?

your code looks ok to me. almost identical to some working code I use

Lee, I am not seeing you set the mime type of the attachments? Have
you set your .mime.types file? If not perhaps you are doing it
programmaticly and in code you did not include?

Here's an example I use for images. You can take pieces from it as
you need:

// Get Image
MimeBodyPart getImagePart() {

MimeBodyPart imgPart = new MimeBodyPart();
String imgFile = "pathtomyimage";
try {

MimetypesFileTypeMap mftm = new MimetypesFileTypeMap();
mftm.addMimeTypes("image/jpeg");
FileDataSource imgFds=new FileDataSource(imgFile);
imgFds.setFileTypeMap(mftm);
imgPart.setDataHandler(new DataHandler(imgFds));

// If you have lots of images in the html you need to set
// this uniquely for each one (i think it is not generated)
imgPart.setContentID ("image1");

} catch (Exception e) {
System.out.println("Error creating image attachment");
System.exit (1);
}

return imgPart;
}
