Hi, I am trying to send a mail with the attachment in RTF format. For this is made a mutipart object, but the moment i set the content type to application/rtf, javamail raises an exception. Is there any other way to specify the rtf format. // Fill the message messageBodyPart.setText(""); multipart.addBodyPart(messageBodyPart); // This is for the attachment. messageBodyPart.setDataHandler(new DataHandler(fileLoaded.toString(), "application/rtf")); multipart.addBodyPart(messageBodyPart); // Put parts in message message.setContent(multipart); // Send the message Transport.send(message);    More>>
