JavaxMail sending PDF as a File

Hi StackOverflow Community,

I'm trying to fix a problem that I have with Javax Mail, I have an SMTP Service that send mails with attachments. I send the PDF correctly and if I look at the email it shows that it's a PDF Document but when I press download save it as a File and cand be opened by acrobat reader properly.

Here's the code where I set the document

...
    byte[] bytearray = "This is a PDF Document".getBytes();
    ByteArrayDataSource bds = new ByteArrayDataSource(bytearray, "application/pdf");
    attachmentBodyPart.setDataHandler(new DataHandler(bds));
    attachmentBodyPart.setFileName("prueba");
    attachmentBodyPart.setHeader("Content-Type", "application/pdf");
    multipart.addBodyPart(attachmentBodyPart);
...

And here's the images of the mail received

email received

Here's how I download it. Download as a file

WHat should I do? What I am missing?

Thanks in advise.

You are simply sending text as a pdf file, which as expected will not be a valid pdf that can be opened by any pdf reader.

You can use some library like iText to create a valid pdf file and then attach it to email.

Sample code using itext:

Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream("iTextHelloWorld.pdf"));

document.open();
Font font = FontFactory.getFont(FontFactory.COURIER, 16, BaseColor.BLACK);
Chunk chunk = new Chunk("Hello World", font);

document.add(chunk);
document.close();
