Problem with PDF reports as attachments

jsinai

We are having a strange problem: we generate BIRT reports and attach them to emails. If users download the reports to their desktop, and open them with a PDF viewer, all is well. However, if they click on them in an email client like a browser, they render as garbage characters. We are correctly setting the mime type in the email. Has anyone ever seen this behavior?

Thanks,
Julian

Are you setting them as attachments?

Jason, thanks for your reply. Yes, as far as I know we are doing it right: 
 
final Multipart multipart = new MimeMultipart(); // create a multi-part message 
multipart.addBodyPart(messageBodyPart); // set text message part 
 
messageBodyPart = new MimeBodyPart(); // part two is attachment 
final DataSource source = new FileDataSource(reportURL); 
messageBodyPart.setDataHandler(new DataHandler(source)); 
messageBodyPart.setFileName(reportURL.substring(reportURL.lastIndexOf("/") + 1, reportURL.length())); 
multipart.addBodyPart(messageBodyPart); 
 
message.setContent(multipart); // send the complete message parts 
Transport.send(message);

Is the report url a completed report, meaning a pdf on the file system?

Jason, thanks for the reply. I solved the problem: a colleague realized that in a multipart message, the mime type of both the body and the attachments need to be set. I was only setting it for the pdf attachment. Once I set the body to text/plain, everything worked.

Glad to read. Just for info, if you use the engine api you can stream report output as an attachment as well. This would mean not writting the output to the file system.

Thanks for the info, that would definitely be more efficient.
