    Asynchronous Mail with attachments

    Matt Davies Newbie

      I'm trying to send an asychronous email with Seam and am running into problems when I try to use the attachment feature.


      I am generating a PDF using iText and creating a byte array.  I put the array into the event context, and when I try to print the array in the email I get the array reference so it appears it is in the event context.


      So, the problem seems to be with the Mime attachment.  Here's what I have.


      Method for sending email


      @Asynchronous
          public void sendEmailGiftCertificate(@Duration long delay, EmailMessageStruct emailMessageStruct) {
             try {
                  GiftCertificatesToPDF g = new GiftCertificatesToPDF();
                     GiftCertInfoStruct params = new GiftCertInfoStruct();
                     params.setEmail("matt@test.com");
                     g.setParams(params);
                     ByteArrayOutputStream baos = g.generatePDF();
                     byte[] contents = baos.toByteArray();
                     System.out.println("Size: " + contents.length );
                     Contexts.getEventContext().set("attachment",contents);
                     
                     baos.close();
                     String orderId = emailMessageStruct.getData();
                    AccountingTransactions xact = em.find(AccountingTransactions.class, orderId);
                     Contexts.getEventContext().set("struct", emailMessageStruct);
                    Contexts.getEventContext().set("xact", xact);
                       
                     Renderer.instance().render("/shop/checkout/includes/emailGiftCertificate.xhtml");
             } catch (Exception e) {
                e.printStackTrace();
             }
          }



      Email snip



      <m:attachment value="#{attachment}" />



      And a portion of the stack trace

      Anyone know how to do an async email with a byte array for an attachment? Is there a better way?



      Thanks!
