  1. POJava mail PDF attachment not working
    text
    copied!<p>I am generating a PDF and trying to attach it to a mail as well as download it from browser using java. Download from browser works fine, but attaching to mail is where I am facing an issue. The file is attached. Attachment name and size of the file are intact. The problem is when I open the PDF from mail attachment, it shows nothing. correct number of pages with no content. When I attach the file downloaded from browser by hardcoding, it works fine. So I suppose the problem is not with the PDF generation. I tried opening both(one downloaded from browser and the other downloaded from mail) the files using comparing tool beyond compare. The one downloaded from mail shows conversion error. When I open with notepad++, both show different encoding. I not very familiar with these encoding thing. I suppose it is something to do with encoding.</p> <p>I also observed that the content in mail download is same as the one at PDF generation. But the one at browser download is different.</p> <p>An excerpt of what I get on browser download is as below(The content is too large to paste) </p> <pre><code>%PDF-1.4 %âãÏÓ 4 0 obj &lt;&lt;/Type/XObject/ColorSpace/DeviceRGB/Subtype/Image/BitsPerComponent 8/Width 193/Length 11222/Height 58/Filter/DCTDecode&gt;&gt;stream ÿØÿà </code></pre> <p>An excerpt of what I get on mail download is as below </p> <pre><code>%PDF-1.4 %???? 4 0 obj &lt;&lt;/Type/XObject/ColorSpace/DeviceRGB/Subtype/Image/BitsPerComponent 8/Width 193/Length 11222/Height 58/Filter/DCTDecode&gt;&gt;stream ???? </code></pre> <p>I am using Spring MimeMessageHelper to send the message. I am using the below method to add attachment</p> <pre><code>MimeMessageHelper.addAttachment(fileName, new ByteArrayResource(attachmentContent.getBytes()), "application/pdf"); </code></pre> <p>I've also tried another way of attaching but in vain</p> <pre><code>DataSource dataSource = new ByteArrayDataSource(bytes, "application/pdf"); MimeBodyPart pdfBodyPart = new MimeBodyPart(); pdfBodyPart.addHeader("Content-Type", "application/pdf;charset=UTF-8"); pdfBodyPart.addHeader("Content-disposition", "attachment; filename="+fileName); pdfBodyPart.setDataHandler(new DataHandler(dataSource)); pdfBodyPart.setFileName(fileName); mimeMessageHelper.getMimeMultipart().addBodyPart(pdfBodyPart); </code></pre> <p>Any help would be greatly appreciated. Thanks in advance</p>
