Issue Emailing Certain PDFs

Question

I have a program that dynamically creates a pdf report in iText and saves it to a folder, where an email is generated with the PDF as an attachment. I have attempted this using both javamail and the commons email from apache, and sometimes it works fine, but sometimes the email just never goes out. In both situations, the file is successfully created (can see it and open it on the local file system) and in both situations all the code is executed, confirmed via print statements. To make matters worse, no errors show up in any logs, not the service I am executing's logs, or the Windows logs on any machien associated with the process.
Has anyone seen this behavior? Either scenarios that might cause this or some method of generating an error would be helpful.
Thanks in advance.

Answer 1

Nope... there is kind of too much code to post, but the class that actually send the email is shown below (ASCIIEmail is an object I wrote... I confirmed the values of each that I am using):
public class EmailDriver
     private static Log myLog = LogFactory.getLog(EmailDriver.class);
     public void sendASCIIEmail(ASCIIEmail email)
          try
               MultiPartEmail sEmail = new MultiPartEmail();
               sEmail.setHostName(email.getHostName());
               sEmail.setFrom(email.getFromEmail().getEmailAddress(), email.getFromEmail().getEmailName());
               for(int i = 0; i < email.getToSize(); i++)
                    sEmail.addTo(email.getTo(i).getEmailAddress(), email.getTo(i).getEmailName());
               for(int i = 0; i < email.getCCSize(); i++)
                    sEmail.addTo(email.getCC(i).getEmailAddress(), email.getCC(i).getEmailName());
               for(int i = 0; i < email.getBCCSize(); i++)
                    sEmail.addTo(email.getBCC(i).getEmailAddress(), email.getBCC(i).getEmailName());
               sEmail.setSubject(email.getSubject());
               sEmail.setMsg(email.getMessage());
               if(email.getAttachmentPath() != null)
                    EmailAttachment attachment = new EmailAttachment();
                    attachment.setPath(email.getAttachmentPath());
                    attachment.setDisposition(EmailAttachment.ATTACHMENT);
                    sEmail.attach(attachment);
               sEmail.send();
          catch(Exception e)
               myLog.error("Failed to send email: " + ExceptionStackPrinter.getStackTrace(e));
}In addition, if I comment out the attachment section it will always send the appropriate emails, and if I try using any illegal commands in here, it logs correctly using the apache log4j.
The part that is extremely confusing is it appears to depend on what I actually put in the pdf file, but I have never failed to actually generate the pdf file. I can always see it on the file system. My best guess is something is probably being formatted differently depending on the pdf content, but without finding any errors anywhere, I have been unable to ascertain exactly what the issue is.
