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

Answer 1

An email message consists of a header and body segment.

Header part will contain from, to and subject.

The body contains the attachments. To support carrying attachments in the body, type Multipart should exists.

The Multipart object holds multiple parts in which each part is represented as a type of BodyPart whose subclass, MimeBodyPart – can take a file as its content.

To add attachments into the mail body MimeBodyPart class provides some convenient methods.

// JavaMail 1.3
MimeBodyPart attachPart = new MimeBodyPart();
String attachFile = "D:/test.pdf";

DataSource source = new FileDataSource(attachFile);
attachPart.setDataHandler(new DataHandler(source));
attachPart.setFileName(new File(attachFile).getName());

multipart.addBodyPart(attachPart);


// JavaMail 1.4
MimeBodyPart attachPart = new MimeBodyPart();
String attachFile = "D:/test.pdf";
attachPart.attachFile(attachFile);
multipart.addBodyPart(attachPart);
