    copied!<p>I'll create a EML file with an attachment using JavaMail. </p> <p>I created a simple EML file successfully, but adding an attachment don't work properly. I'm going to add a PDF file. My EML file will be created successfully. If I open the generated EML file with Outlook I'll find not my PDF file as attachment but I'll find the EML file itself as attachment. Does anyone has an idea? </p> <p>I tried two variants (with same result), I used the <code>FileDataSource</code> class and the simple way with <code>MimeBodyPart#attachFile(File)</code>. </p> <p>I'm going to post an example:</p> <pre><code>File pdfFile = new File("somePdfFile"); Properties p = System.getProperties(); Session session = Session.getInstance(p); MimeMessage message = new MimeMessage(session); // MimeBodyPart txt = new MimeBodyPart(); // txt.setText(""); MimeBodyPart mbp = new MimeBodyPart(); mbp.attachFile(attachment); // FileDataSource fds = new FileDataSource(attachment); // fds.setFileTypeMap(new FileTypeMap() { // // @Override // public String getContentType(String arg0) { // return "application/pdf"; // } // // @Override // public String getContentType(File file) { // return "application/pdf"; // } // // }); // mbp.setDataHandler(new DataHandler(fds)); // mbp.setFileName("\"" + attachment.getName() + "\""); // mbp.setDisposition(MimePart.ATTACHMENT); // mbp.setHeader("Content-ID", "Attachment"); Multipart mp = new MimeMultipart(); // mp.addBodyPart(txt); mp.addBodyPart(mbp); message.setContent(mp); File emlFile = new File("message.eml"); emlFile.createNewFile(); message.writeTo(new FileOutputStream(emlFile)); // do something with the EML file // Desktop.getDesktop().open(emlFile); </code></pre> <p><a href="https://stackoverflow.com/questions/157195/create-an-eml-e-mail-file-in-java">Create a .eml (email) file in Java</a></p> <hr> <p>Thank you for your response. I uploaded a PDF file (that I use for testing, it's a simple HelloWorld generated with Crystal Reports) and the generated EML file which should include the PDF file.</p> <p>I just noticed that if I open the linked EML file with Apple Mail or with Outlook Express it works (but without edit possibility). Maybe it's an issue of Microsoft Outlook?</p> <p><em>The links are removed</em></p>
