Adding message parts

You may create multi-part MIME messages by adding one MIME message to another using the MimeMessage#addPart method.

Example

// body text for plain text part

String plainText = "This is plain text";

// body text for html text part

String htmlText = "<b>This is HTML text</b>";

// create parent message

MimeMessage contents = new MimeMessage();

// set Content-Type header to multipart/alternative

contents.setContentType("multipart/alternative");

// create plain text part and add to parent

try {

 MimeMessage plainMessage = new MimeMessage();

 plainMessage.setContentType("text/plain");

 plainMessage.setBody(plainText);

 contents.addPart(plainMessage);

} catch (Exception e) {

 System.out.println(e);

}

// create html text part and add to parent

try {

 MimeMessage htmlMessage = new MimeMessage();

 htmlMessage.setContentType("text/html");

 htmlMessage.setBody(htmlText);

 contents.addPart(htmlMessage);

} catch (Exception e) {

 System.out.println(e);

}
