Send e-mail in Pdf attachment as stream

Question

I want to send a Pdf as an e-mail attachment (I am using the JavaMail API ). I have the Pdf (generated by jasper) as an byte[].

public InputStre         


        

Answer 1

The constructor you used is for parsing a mime part from the transport.

Your second example should work out right. You may consider

• not to convert to InputStream and back, this will make unnecessary copies
• add a disposition ( e.g. bp.setDisposition(Part.ATTACHMENT); )

Answer 2

I have found a solution as suggested in this thread. It seems that there is a DataSource class created just for this purpose. Hope this example will help others also.

    if (arrayInputStream != null && arrayInputStream instanceof ByteArrayInputStream) {
        // create the second message part with the attachment from a OutputStrean
        MimeBodyPart attachment= new MimeBodyPart();
        ByteArrayDataSource ds = new ByteArrayDataSource(arrayInputStream, "application/pdf"); 
        attachment.setDataHandler(new DataHandler(ds));
        attachment.setFileName("Report.pdf");
        mimeMultipart.addBodyPart(attachment);
    }
